Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Track decrypted status in vmbus_gpadl
In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.
In order to make sure callers of vmbus_establish_gpadl() and
vmbus_teardown_gpadl() don't return decrypted/shared pages to
allocators, add a field in struct vmbus_gpadl to keep track of the
decryption status of the buffers. This will allow the callers to
know if they should free or leak the pages.

The attacker holds no console, shell, or account on the guest, so this is not a locally-accessed attack.\nAC:L - The host deterministically controls the outcome by returning a failure status from `HVCALL_MODIFY_SPARSE_GPA_PAGE_HOST_VISIBILITY`, and it also controls when GPADLs are established and torn down via channel offer/rescind, so it can repeat the cycle at will. No race, no memory layout it cannot influence, and no condition outside its control is involved.\nPR:N - The vulnerable component is the confidential guest kernel, in which the malicious host is by design an unprivileged, untrusted entity \u2014 the whole point of SEV-SNP/TDX is that the VMM has no rights over guest memory. Exploitation requires no guest credential, capability, or account whatsoever.\nUI:N - The host triggers the establish/teardown paths itself through channel rescind/re-offer and NVSP buffer negotiation, and netvsc/uio_hv_generic probe and removal run automatically. No guest administrator or user action is needed.\nS:C - The failure defeats the hardware/firmware-enforced confidential-computing memory boundary (SEV-SNP RMP / TDX module), a security authority distinct from the guest OS, letting the VMM access memory the platform was supposed to keep private \u2014 directly analogous to an IOMMU/DMA boundary bypass. Impact therefore extends beyond the guest kernel\u0027s own security scope.\nC:H - Shared pages returned to the buddy allocator are reused for arbitrary guest kernel and userspace memory while the VMM still maps their shared alias in the EPT/NPT, giving it plaintext read of whatever lands there \u2014 keys, credentials, and application data. That is a total loss of the confidential VM\u0027s confidentiality guarantee.\nI:H - The shared alias is writable by the VMM, so the host can modify guest memory that has been reallocated for page tables, task structs, or page-cache-backed code, yielding an arbitrary kernel write and control-flow hijack primitive inside the guest. The host can additionally groom placement by repeatedly forcing multi-megabyte netvsc buffers through the leak.\nA:H - Reusing pages whose actual shared/private state disagrees with the guest PTE causes data corruption and faults, and the host can unmap or alter the shared backing to crash the guest; on TDX/SNP such state mismatches escalate to fatal guest errors. The WARN added in the same series also panics guests configured with `panic_on_warn`."

[ 33.482978] ==================================================================
We find the root cause of this OOB is that arm does not clear stale stack
poison in the case of cpuidle.
This patch refer to arch/arm64/kernel/sleep.S to resolve this issue.
From cited commit [1] that explain the problem
Functions which the compiler has instrumented for KASAN place poison on
the stack shadow upon entry and remove this poison prior to returning.
In the case of cpuidle, CPUs exit the kernel a number of levels deep in
C code. Any instrumented functions on this critical path will leave
portions of the stack shadow poisoned.
If CPUs lose context and return to the kernel via a cold path, we
restore a prior context saved in __cpu_suspend_enter are forgotten, and
we never remove the poison they placed in the stack shadow area by
functions calls between this and the actual exit of the kernel.
Thus, (depending on stackframe layout) subsequent calls to instrumented
functions may hit this stale poison, resulting in (spurious) KASAN
splats to the console.
To avoid this, clear any stale poison from the idle thread for a CPU
prior to bringing a CPU online.
From cited commit [2]
Extend to check for CONFIG_KASAN_STACK
[1] commit 0d97e6d8024c ("arm64: kasan: clear stale stack poison")

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix module reference leakage from bdev_open_by_dev error path
At the time bdev_may_open() is called, module reference is grabbed
already, hence module reference should be released if bdev_may_open()
failed.
This problem is found by code review.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedf: Ensure the copied buf is NUL terminated
Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout
There is a race condition between l2cap_chan_timeout() and
l2cap_chan_del(). When we use l2cap_chan_del() to delete the
channel, the chan->conn will be set to null. But the conn could
be dereferenced again in the mutex_lock() of l2cap_chan_timeout().
As a result the null pointer dereference bug will happen. The
KASAN report triggered by POC is shown below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: stk1160: fix bounds checking in stk1160_copy_video()
The subtract in this condition is reversed. The ->length is the length
of the buffer. The ->bytesused is how many bytes we have copied thus
far. When the condition is reversed that means the result of the
subtraction is always negative but since it's unsigned then the result
is a very high positive value. That means the overflow check is never
true.
Additionally, the ->bytesused doesn't actually work for this purpose
because we're not writing to "buf->mem + buf->bytesused". Instead, the
math to calculate the destination where we are writing is a bit
involved. You calculate the number of full lines already written,
multiply by two, skip a line if necessary so that we start on an odd
numbered line, and add the offset into the line.
To fix this buffer overflow, just take the actual destination where we
are writing, if the offset is already out of bounds print an error and
return. Otherwise, write up to buf->length bytes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow
There is a possibility of buffer overflow in
show_rcu_tasks_trace_gp_kthread() if counters, passed
to sprintf() are huge. Counter numbers, needed for this
are unrealistically high, but buffer overflow is still
possible.
Use snprintf() with buffer size instead of sprintf().
Found by Linux Verification Center (linuxtesting.org) with SVACE.

The most severe defensible vector is a local actor on the machine.\nAC:H - Overflow requires the four unsigned long counters to render to \u226564 decimal digits, i.e. three monotonic heavy-reader counters near 10^18 simultaneously, which no attacker can drive within any feasible uptime; it additionally requires non-default builds/boot options (CONFIG_TASKS_TRACE_RCU_READ_MB plus CONFIG_PROVE_RCU, rcutorture, or rcutree.sysrq_rcu=1). These are conditions entirely outside the attacker\u0027s control.\nPR:L - No capability check guards the counter-incrementing paths, so an unprivileged local user\u0027s workload is the lowest-privileged plausible actor; scoring the higher-severity option, PR:L rather than PR:H is used even though the actual dump trigger (sysrq, rcutorture) normally implies root.\nUI:N - Emission of the RCU kthread dump happens from kernel diagnostic paths without any victim action; no user must open a file, mount a filesystem, or interact in any way.\nS:U - The stack overflow corrupts the kernel stack of the thread executing the dump, staying entirely within the kernel\u0027s own security authority with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The defect is an out-of-bounds stack write that can clobber the canary, saved registers, and return address; per kernel scoring guidance such memory corruption is treated as leverageable toward disclosure of kernel memory, even though the overflowing bytes themselves are uncontrolled ASCII digits and there is no direct read primitive.\nI:H - This is a classic out-of-bounds stack write of up to 23 bytes past a 64-byte buffer, overwriting adjacent frame state including the saved return address, which is scored as high integrity impact for control-flow corruption.\nA:H - Smashing the stack frame triggers __stack_chk_fail (panic) on stack-protector builds and a fatal fault on a garbage return address otherwise, i.e. a kernel crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
qibfs: fix dentry leak
simple_recursive_removal() drops the pinning references to all positives
in subtree. For the cases when its argument has been kept alive by
the pinning alone that's exactly the right thing to do, but here
the argument comes from dcache lookup, that needs to be balanced by
explicit dput().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf
If ->ProtocolId is SMB2_TRANSFORM_PROTO_NUM, smb2 request size
validation could be skipped. if request size is smaller than
sizeof(struct smb2_query_info_req), slab-out-of-bounds read can happen in
smb2_allocate_rsp_buf(). This patch allocate response buffer after
decrypting transform request. smb3_decrypt_req() will validate transform
request size and avoid slab-out-of-bound in smb2_allocate_rsp_buf().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: Fix Use-After-Free in ovs_ct_exit
Since kfree_rcu, which is called in the hlist_for_each_entry_rcu traversal
of ovs_ct_limit_exit, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.

No remote packet processing reaches `ovs_ct_limit_exit`.\nAC:L - The attacker controls every input to the race \u2014 chain length (up to 65536 zone entries across 512 buckets), CPU contention to force preemption of the traversal, heap spray to reclaim the freed `struct ovs_ct_limit`, and unlimited free retries by looping namespace create/destroy. Nothing essential to triggering it lies outside attacker influence.\nPR:L - `OVS_CT_LIMIT_CMD_SET` uses `GENL_UNS_ADMIN_PERM`, which checks `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`, so an unprivileged user obtains it via `unshare -Urn`; the family is `netnsok` and the module autoloads through `MODULE_ALIAS_GENL_FAMILY` with no capability gate in `ctrl_getfamily()`.\nUI:N - The attacker performs every step alone \u2014 creating the namespace, setting zone limits, and exiting the namespace to drive the teardown. No victim action or interaction is involved.\nS:U - The corruption is confined to kernel slab memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is a standard kernel local privilege-escalation scope.\nC:H - The use-after-free lets the attacker place controlled data in the freed object and steer the traversal to arbitrary kernel addresses, and the resulting arbitrary-free primitive enables controlled UAFs elsewhere that expose arbitrary kernel memory.\nI:H - A reclaimed object supplies an attacker-chosen `next` pointer that is passed to `kfree_rcu()`, yielding an arbitrary-address `kvfree()` plus pointer writes into `rcu_head-\u003efunc`/`-\u003enext` \u2014 a write primitive sufficient for control-flow hijacking and privilege escalation.\nA:H - Dereferencing and then RCU-freeing a stale list pointer corrupts slab metadata and reliably produces a kernel oops or panic even in unsuccessful exploitation attempts, and the path can be re-triggered at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: avoid off-by-one read from userspace
We try to access count + 1 byte from userspace with memdup_user(buffer,
count + 1). However, the userspace only provides buffer of count bytes and
only these count bytes are verified to be okay to access. To ensure the
copied buffer is NUL terminated, we use memdup_user_nul instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix potential glock use-after-free on unmount
When a DLM lockspace is released and there ares still locks in that
lockspace, DLM will unlock those locks automatically. Commit
fb6791d100d1b started exploiting this behavior to speed up filesystem
unmount: gfs2 would simply free glocks it didn't want to unlock and then
release the lockspace. This didn't take the bast callbacks for
asynchronous lock contention notifications into account, which remain
active until until a lock is unlocked or its lockspace is released.
To prevent those callbacks from accessing deallocated objects, put the
glocks that should not be unlocked on the sd_dead_glocks list, release
the lockspace, and only then free those glocks.
As an additional measure, ignore unexpected ast and bast callbacks if
the receiving glock is dead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: refine the EOF check in blkdev_iomap_begin
blkdev_iomap_begin rounds down the offset to the logical block size
before stashing it in iomap->offset and checking that it still is
inside the inode size.
Check the i_size check to the raw pos value so that we don't try a
zero size write if iter->pos is unaligned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/amd/pm: fix a use-after-free in kv_parse_power_table
When ps allocated by kzalloc equals to NULL, kv_parse_power_table
frees adev->pm.dpm.ps that allocated before. However, after the control
flow goes through the following call chains:
kv_parse_power_table
|-> kv_dpm_init
|-> kv_dpm_sw_init
|-> kv_dpm_fini
The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its
first free in kv_parse_power_table and causes a use-after-free bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Prevent double free on error
The error handling path in its_vpe_irq_domain_alloc() causes a double free
when its_vpe_init() fails after successfully allocating at least one
interrupt. This happens because its_vpe_irq_domain_free() frees the
interrupts along with the area bitmap and the vprop_page and
its_vpe_irq_domain_alloc() subsequently frees the area bitmap and the
vprop_page again.
Fix this by unconditionally invoking its_vpe_irq_domain_free() which
handles all cases correctly and by removing the bitmap/vprop_page freeing
from its_vpe_irq_domain_alloc().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE
bpf_prog_attach uses attach_type_to_prog_type to enforce proper
attach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses
bpf_prog_get and relies on bpf_prog_attach_check_attach_type
to properly verify prog_type <> attach_type association.
Add missing attach_type enforcement for the link_create case.
Otherwise, it's currently possible to attach cgroup_skb prog
types to other cgroup hooks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
eth: sungem: remove .ndo_poll_controller to avoid deadlocks
Erhard reports netpoll warnings from sungem:
netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398)
WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c
gem_poll_controller() disables interrupts, which may sleep.
We can't sleep in netpoll, it has interrupts disabled completely.
Strangely, gem_poll_controller() doesn't even poll the completions,
and instead acts as if an interrupt has fired so it just schedules
NAPI and exits. None of this has been necessary for years, since
netpoll invokes NAPI directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: bnx2fc: Remove spin_lock_bh while releasing resources after upload
The session resources are used by FW and driver when session is offloaded,
once session is uploaded these resources are not used. The lock is not
required as these fields won't be used any longer. The offload and upload
calls are sequential, hence lock is not required.
This will suppress following BUG_ON():

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: fix overwriting ct original tuple for ICMPv6
OVS_PACKET_CMD_EXECUTE has 3 main attributes:
- OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format.
- OVS_PACKET_ATTR_PACKET - Binary packet content.
- OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.
OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure
with the metadata like conntrack state, input port, recirculation id,
etc. Then the packet itself gets parsed to populate the rest of the
keys from the packet headers.
Whenever the packet parsing code starts parsing the ICMPv6 header, it
first zeroes out fields in the key corresponding to Neighbor Discovery
information even if it is not an ND packet.
It is an 'ipv6.nd' field. However, the 'ipv6' is a union that shares
the space between 'nd' and 'ct_orig' that holds the original tuple
conntrack metadata parsed from the OVS_PACKET_ATTR_KEY.
ND packets should not normally have conntrack state, so it's fine to
share the space, but normal ICMPv6 Echo packets or maybe other types of
ICMPv6 can have the state attached and it should not be overwritten.
The issue results in all but the last 4 bytes of the destination
address being wiped from the original conntrack tuple leading to
incorrect packet matching and potentially executing wrong actions
in case this packet recirculates within the datapath or goes back
to userspace.
ND fields should not be accessed in non-ND packets, so not clearing
them should be fine. Executing memset() only for actual ND packets to
avoid the issue.
Initializing the whole thing before parsing is needed because ND packet
may not contain all the options.
The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't
affect packets entering OVS datapath from network interfaces, because
in this case CT metadata is populated from skb after the packet is
already parsed.

OVS is the data plane on hypervisors and Kubernetes nodes handling untrusted tenant and internet traffic.\nAC:L - Any ordinary non-ND ICMPv6 packet (e.g. an Echo Request) carrying conntrack state deterministically wipes the original tuple \u2014 there is no race, no memory-layout dependency, and no condition outside the attacker\u0027s control. CONFIG_OPENVSWITCH with conntrack/ct_orig matching is the default configuration in OVN, OpenStack and Antrea deployments.\nPR:N - The remote sender of the ICMPv6 packet needs no credentials; the privileged netlink call is issued by the trusted ovs-vswitchd on the packet\u0027s behalf as part of normal slow-path processing. Even the direct local trigger only needs CAP_NET_ADMIN in a user namespace (GENL_UNS_ADMIN_PERM with netnsok=true), i.e. no more than PR:L.\nUI:N - Triggering requires only that the packet traverse the OVS datapath; no administrator or user action is needed beyond the normal operation of the virtual switch.\nS:C - The OVS datapath is the enforcement point for isolation and ACLs between separate VMs, containers and tenants, so mismatched flows cause traffic to be handled under a different security authority\u0027s policy. The corrupted key is additionally exported to the userspace control plane, which installs datapath flows for other workloads based on it.\nC:H - Wiping the conntrack original tuple makes stateful ACLs and un-DNAT rules keyed on ct_ipv6_src/ct_ipv6_dst fail to match, so packets can fall through to a different flow and be output to an unintended port or allowed through to a protected endpoint, exposing traffic and services to parties that should not reach them.\nI:H - The kernel destroys control-plane-supplied conntrack metadata, so the datapath executes actions the controller never intended, and the bogus tuple returned on upcall causes a wrong megaflow to be installed for subsequent traffic \u2014 a persistent subversion of the virtual switch\u0027s forwarding and filtering policy.\nA:H - Affected connections are mis-forwarded or black-holed because the reply traffic no longer matches the established/un-DNAT flow, and the wrong megaflow installed from the corrupted key keeps denying connectivity for the whole class of traffic it wildcards until it is evicted."

The `entries` value it influences is already fully attacker-supplied through the legitimate path, so no integrity is gained.\nA:H - The access is a KASAN-detected slab out-of-bounds read that produces a kernel splat and panics on builds running `panic_on_warn`, and the resulting garbage ring size drives failing large vmalloc allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix deadlock in usb_deauthorize_interface()
Among the attribute file callback routines in
drivers/usb/core/sysfs.c, the interface_authorized_store() function is
the only one which acquires a device lock on an ancestor device: It
calls usb_deauthorize_interface(), which locks the interface's parent
USB device.
The will lead to deadlock if another process already owns that lock
and tries to remove the interface, whether through a configuration
change or because the device has been disconnected. As part of the
removal procedure, device_del() waits for all ongoing sysfs attribute
callbacks to complete. But usb_deauthorize_interface() can't complete
until the device lock has been released, and the lock won't be
released until the removal has finished.
The mechanism provided by sysfs to prevent this kind of deadlock is
to use the sysfs_break_active_protection() function, which tells sysfs
not to wait for the attribute callback.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: core: delete incorrect free in pinctrl_enable()
The "pctldev" struct is allocated in devm_pinctrl_register_and_init().
It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),
so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys
the mutex as well.

Once the free happens the devres release is guaranteed to run on the dangling pointer, so no unwinnable race is required.\nPR:L - An unprivileged local account suffices to apply the allocation pressure that induces the `pinctrl_claim_hogs()` error path on a system where an affected pinctrl driver probes or re-probes. No capability check guards `pinctrl_enable()` itself, and the resulting double free is in shared kernel slab state.\nUI:N - The vulnerable path executes autonomously during driver probe and devres teardown; no victim action such as mounting a filesystem or opening a file is needed.\nS:U - The corruption is confined to kernel slab memory within the same security authority \u2014 a standard kernel-level compromise with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - `pinctrl_unregister()` reads extensively through the freed `pctldev` (`-\u003emutex`, `-\u003enode`, `-\u003edesc-\u003epins`, `-\u003ep`), and if the slab object is reclaimed by attacker-groomed data the double free enables heap-layout manipulation that can be leveraged into arbitrary kernel memory disclosure.\nI:H - The stale `list_del(\u0026pctldev-\u003enode)` writes through `next`/`prev` pointers in freed \u2014 and potentially attacker-controlled \u2014 memory, giving a write-what-where primitive, while the second `kfree()` corrupts the slab freelist and permits overlapping-allocation attacks leading to control-flow hijack.\nA:H - Double free plus use-after-free reliably corrupts the SLUB freelist and locks/destroys an already-destroyed mutex, producing an oops or panic; drivers that ignore `pinctrl_enable()`\u0027s return value (e.g. sppctl) leave a dangling pointer live until unbind, guaranteeing a later crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()
lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the
hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the
hbalock to avoid potential deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix access violation during port device removal
Testing with KASAN and syzkaller revealed a bug in port.c:disable_store():
usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to
is concurrently removed, but the function does not check for this
possibility before dereferencing the returned value.
It turns out that the first dereference is unnecessary, since hub->intfdev
is the parent of the port device, so it can be changed easily. Adding a
check for hub == NULL prevents further problems.
The same bug exists in the disable_show() routine, and it can be fixed the
same way.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix shift-out-of-bounds in dctcp_update_alpha().
In dctcp_update_alpha(), we use a module parameter dctcp_shift_g
as follows:
alpha -= min_not_zero(alpha, alpha >> dctcp_shift_g);
...
delivered_ce <<= (10 - dctcp_shift_g);
It seems syzkaller started fuzzing module parameters and triggered
shift-out-of-bounds [0] by setting 100 to dctcp_shift_g:
memcpy((void*)0x20000080,
"/sys/module/tcp_dctcp/parameters/dctcp_shift_g\000", 47);
res = syscall(__NR_openat, /*fd=*/0xffffffffffffff9cul, /*file=*/0x20000080ul,
/*flags=*/2ul, /*mode=*/0ul);
memcpy((void*)0x20000000, "100\000", 4);
syscall(__NR_write, /*fd=*/r[0], /*val=*/0x20000000ul, /*len=*/4ul);
Let's limit the max value of dctcp_shift_g by param_set_uint_minmax().
With this patch:
# echo 10 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
# cat /sys/module/tcp_dctcp/parameters/dctcp_shift_g
10
# echo 11 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
-bash: echo: write error: Invalid argument
[0]:
UBSAN: shift-out-of-bounds in net/ipv4/tcp_dctcp.c:143:12

Summary
In the Linux kernel, the following vulnerability has been resolved:
libbpf: Prevent null-pointer dereference when prog to load has no BTF
In bpf_objec_load_prog(), there's no guarantee that obj->btf is non-NULL
when passing it to btf__fd(), and this function does not perform any
check before dereferencing its argument (as bpf_object__btf_fd() used to
do). As a consequence, we get segmentation fault errors in bpftool (for
example) when trying to load programs that come without BTF information.
v2: Keep btf__fd() in the fix instead of reverting to bpf_object__btf_fd().

Summary
In the Linux kernel, the following vulnerability has been resolved:
m68k: Fix spinlock race in kernel thread creation
Context switching does take care to retain the correct lock owner across
the switch from 'prev' to 'next' tasks. This does rely on interrupts
remaining disabled for the entire duration of the switch.
This condition is guaranteed for normal process creation and context
switching between already running processes, because both 'prev' and
'next' already have interrupts disabled in their saved copies of the
status register.
The situation is different for newly created kernel threads. The status
register is set to PS_S in copy_thread(), which does leave the IPL at 0.
Upon restoring the 'next' thread's status register in switch_to() aka
resume(), interrupts then become enabled prematurely. resume() then
returns via ret_from_kernel_thread() and schedule_tail() where run queue
lock is released (see finish_task_switch() and finish_lock_switch()).
A timer interrupt calling scheduler_tick() before the lock is released
in finish_task_switch() will find the lock already taken, with the
current task as lock owner. This causes a spinlock recursion warning as
reported by Guenter Roeck.
As far as I can ascertain, this race has been opened in commit
533e6903bea0 ("m68k: split ret_from_fork(), simplify kernel_thread()")
but I haven't done a detailed study of kernel history so it may well
predate that commit.
Interrupts cannot be disabled in the saved status register copy for
kernel threads (init will complain about interrupts disabled when
finally starting user space). Disable interrupts temporarily when
switching the tasks' register sets in resume().
Note that a simple oriw 0x700,%sr after restoring sr is not enough here
- this leaves enough of a race for the 'spinlock recursion' warning to
still be observed.
Tested on ARAnyM and qemu (Quadra 800 emulation).

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix missing hugetlb_lock for resv uncharge
There is a recent report on UFFDIO_COPY over hugetlb:
https://lore.kernel.org/all/000000000000ee06de0616177560@google.com/
350: lockdep_assert_held(&hugetlb_lock);
Should be an issue in hugetlb but triggered in an userfault context, where
it goes into the unlikely path where two threads modifying the resv map
together. Mike has a fix in that path for resv uncharge but it looks like
the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd()
will update the cgroup pointer, so it requires to be called with the lock
held.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: prevent NULL dereference in ip6_output()
According to syzbot, there is a chance that ip6_dst_idev()
returns NULL in ip6_output(). Most places in IPv6 stack
deal with a NULL idev just fine, but not here.
syzbot reported:

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: savage: Handle err return when savagefb_check_var failed
The commit 04e5eac8f3ab("fbdev: savage: Error out if pixclock equals zero")
checks the value of pixclock to avoid divide-by-zero error. However
the function savagefb_probe doesn't handle the error return of
savagefb_check_var. When pixclock is 0, it will cause divide-by-zero error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: prevent mss overflow in skb_segment()
Once again syzbot is able to crash the kernel in skb_segment() [1]
GSO_BY_FRAGS is a forbidden value, but unfortunately the following
computation in skb_segment() can reach it quite easily :
mss = mss * partial_segs;
65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to
a bad final result.
Make sure to limit segmentation so that the new mss value is smaller

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: Handle error of rpc_proc_register() in nfs_net_init().
syzkaller reported a warning [0] triggered while destroying immature
netns.
rpc_proc_register() was called in init_nfs_fs(), but its error
has been ignored since at least the initial commit 1da177e4c3f4
("Linux-2.6.12-rc2").
Recently, commit d47151b79e32 ("nfs: expose /proc/net/sunrpc/nfs
in net namespaces") converted the procfs to per-netns and made
the problem more visible.
Even when rpc_proc_register() fails, nfs_net_init() could succeed,
and thus nfs_net_exit() will be called while destroying the netns.
Then, remove_proc_entry() will be called for non-existing proc
directory and trigger the warning below.
Let's handle the error of rpc_proc_register() properly in nfs_net_init().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: pcie: handle randbuf allocation failure
The kzalloc() in brcmf_pcie_download_fw_nvram() will return null
if the physical memory has run out. As a result, if we use
get_random_bytes() to generate random bytes in the randbuf, the
null pointer dereference bug will happen.
In order to prevent allocation failure, this patch adds a separate
function using buffer on kernel stack to generate random bytes in
the randbuf, which could prevent the kernel stack from overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
r8169: Fix possible ring buffer corruption on fragmented Tx packets.
An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.
This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().
To fix this, postpone inspecting nr_frags until after any padding has been
applied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: Avoid address calculations via out of bounds array indexing
Before request->channels[] can be used, request->n_channels must be set.
Additionally, address calculations for memory after the "channels" array
need to be calculated from the allocation base ("request") rather than
via the first "out of bounds" index of "channels", otherwise run-time
bounds checking will throw a warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: HCI: Remove HCI_AMP support
Since BT_HS has been remove HCI_AMP controllers no longer has any use so
remove it along with the capability of creating AMP controllers.
Since we no longer need to differentiate between AMP and Primary
controllers, as only HCI_PRIMARY is left, this also remove
hdev->dev_type altogether.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: explicitly null-terminate the xattr list
When setting an xattr, explicitly null-terminate the xattr list. This
eliminates the fragile assumption that the unused xattr space is always
zeroed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix garbage collector racing against connect()
Garbage collector does not take into account the risk of embryo getting
enqueued during the garbage collection. If such embryo has a peer that
carries SCM_RIGHTS, two consecutive passes of scan_children() may see a
different set of children. Leading to an incorrectly elevated inflight
count, and then a dangling pointer within the gc_inflight_list.
sockets are AF_UNIX/SOCK_STREAM
S is an unconnected socket
L is a listening in-flight socket bound to addr, not in fdtable
V's fd will be passed via sendmsg(), gets inflight count bumped
connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- -----------
NS = unix_create1()
skb1 = sock_wmalloc(NS)
L = unix_find_other(addr)
unix_state_lock(L)
unix_peer(S) = NS
// V count=1 inflight=0
NS = unix_peer(S)
skb2 = sock_alloc()
skb_queue_tail(NS, skb2[V])
// V became in-flight
// V count=2 inflight=1
close(V)
// V count=1 inflight=1
// GC candidate condition met
for u in gc_inflight_list:
if (total_refs == inflight_refs)
add u to gc_candidates
// gc_candidates={L, V}
for u in gc_candidates:
scan_children(u, dec_inflight)
// embryo (skb1) was not
// reachable from L yet, so V's
// inflight remains unchanged
__skb_queue_tail(L, skb1)
unix_state_unlock(L)
for u in gc_candidates:
if (u.inflight)
scan_children(u, inc_inflight_move_tail)
// V count=1 inflight=2 (!)
If there is a GC-candidate listening socket, lock/unlock its state. This
makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if
there is another embryo coming, it can not possibly carry SCM_RIGHTS. At
this point, unix_inflight() can not happen because unix_gc_lock is already
taken. Inflight graph remains unaffected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/slub: avoid zeroing outside-object freepointer for single free
Commit 284f17ac13fe ("mm/slub: handle bulk and single object freeing
separately") splits single and bulk object freeing in two functions
slab_free() and slab_free_bulk() which leads slab_free() to call
slab_free_hook() directly instead of slab_free_freelist_hook().
If `init_on_free` is set, slab_free_hook() zeroes the object.
Afterward, if `slub_debug=F` and `CONFIG_SLAB_FREELIST_HARDENED` are
set, the do_slab_free() slowpath executes freelist consistency
checks and try to decode a zeroed freepointer which leads to a
"Freepointer corrupt" detection in check_object().
During bulk free, slab_free_freelist_hook() isn't affected as it always
sets it objects freepointer using set_freepointer() to maintain its
reconstructed freelist after `init_on_free`.
For single free, object's freepointer thus needs to be avoided when
stored outside the object if `init_on_free` is set. The freepointer left
as is, check_object() may later detect an invalid pointer value due to
objects overflow.
To reproduce, set `slub_debug=FU init_on_free=1 log_level=7` on the
command line of a kernel build with `CONFIG_SLAB_FREELIST_HARDENED=y`.

The freepointer left\nas is, check_object() may later detect an invalid pointer value due to\nobjects overflow.\n\nTo reproduce, set `slub_debug=FU init_on_free=1 log_level=7` on the\ncommand line of a kernel build with `CONFIG_SLAB_FREELIST_HARDENED=y`.\n\ndmesg sample log:\n[ 10.708715] =============================================================================\n[ 10.710323] BUG kmalloc-rnd-05-32 (Tainted: G B T ): Freepointer corrupt\n[ 10.712695] -----------------------------------------------------------------------------\n[ 10.712695]\n[ 10.712695] Slab 0xffffd8bdc400d580 objects=32 used=4 fp=0xffff9d9a80356f80 flags=0x200000000000a00(workingset|slab|node=0|zone=2)\n[ 10.716698] Object 0xffff9d9a80356600 @offset=1536 fp=0x7ee4f480ce0ecd7c\n[ 10.716698]\n[ 10.716698] Bytes b4 ffff9d9a803565f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n[ 10.720703] Object ffff9d9a80356600: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n[ 10.720703] Object ffff9d9a80356610: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n[ 10.724696] Padding ffff9d9a8035666c: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n[ 10.724696] Padding ffff9d9a8035667c: 00 00 00 00 ....\n[ 10.724696] FIX kmalloc-rnd-05-32: Object at 0xffff9d9a80356600 not freed"

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: make sure to pull inner header in geneve_rx()
syzbot triggered a bug in geneve_rx() [1]
Issue is similar to the one I fixed in commit 8d975c15c0cd
("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

"value": "AV:N - The vulnerable code is the GENEVE UDP encapsulation receive handler for a socket bound to INADDR_ANY on UDP port 6081, reached directly from `udp_rcv()` on a received packet. In collect_md/external mode (standard OVS/OVN cloud overlay) `geneve_lookup_skb()` accepts any remote source address, so any host that can send UDP to the tunnel endpoint reaches `geneve_rx()`.\nAC:L - The attacker fully controls the skb layout: sending the encapsulated packet as IP fragments makes `ip_defrag()` produce a frag_list skb whose linear area ends exactly at the inner Ethernet header, deterministically placing `skb-\u003edata` at `skb-\u003etail` before the ECN read. Outer IP options and geneve option length give additional 4-byte tuning for NIC-driven fragment layouts.\nPR:N - There is no authentication, capability check, or credential validation anywhere on the `ip_rcv` \u2192 `udp_rcv` \u2192 `geneve_udp_encap_recv` \u2192 `geneve_rx` path. An unauthenticated remote peer only needs to send a crafted UDP datagram to the tunnel port.\nUI:N - The bug triggers entirely during softirq packet receive processing on the target host; no local user has to open, mount, or interact with anything.\nS:U - The uninitialized read occurs in kernel network receive context and its effects (ECN decision, packet drop) stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:L - The bug reads uninitialized kernel heap memory past the end of the valid skb data, but is strictly bounded to 1 byte (IPv4 TOS) or 2 bytes (IPv6 dsfield) and stays inside the `skb-\u003ehead` allocation. The stale contents are not returned to the attacker directly \u2014 they leak only as a per-packet drop/no-drop oracle from `__INET_ECN_decapsulate()`.\nI:L - The uninitialized byte drives whether the decapsulated packet is dropped and whether CE/ECT(1) marking is applied to tunneled traffic, so data traversing the tunnel can be modified or discarded based on garbage. The amount is minimal and the attacker has no control over the consequence; `INET_ECN_set_ce()`/`set_ect1()` are bounds-checked, so no out-of-bounds write primitive exists.\nA:L - Incorrect ECN decapsulation driven by uninitialized memory causes spurious drops of legitimate GENEVE-tunneled traffic (`err \u003e 1` \u2192 `kfree_skb`), degrading overlay connectivity. There is no kernel crash on production configurations \u2014 the read stays within the `skb-\u003ehead` slab object so KASAN does not fire, and only the KMSAN debug tool reports it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: core: reject skb_copy(_expand) for fraglist GSO skbs
SKB_GSO_FRAGLIST skbs must not be linearized, otherwise they become
invalid. Return NULL if such an skb is passed to skb_copy or
skb_copy_expand, in order to prevent a crash on a potential later
call to skb_gso_segment.

No out-of-bounds read, uninitialized data, or kernel pointer is exposed to the attacker.\nI:N - Nothing is written outside the skb before the oops \u2014 only the packet\u0027s own UDP length field is updated in `__udp_gso_segment_list()`. There is no out-of-bounds write, use-after-free, or type confusion, so no control-flow-hijack or arbitrary-write primitive arises.\nA:H - The NULL dereference happens in softirq context on the transmit path, producing a kernel oops that on a forwarding device typically panics the machine (and is fatal with `panic_on_oops`). An unauthenticated attacker can repeat it at will with a UDP burst, causing complete loss of availability."

No local access, and no RDMA fabric connectivity to the attacker is needed since the handshake is ordinary TCP.\nAC:L - The missing `neigh_release()`/`ip_rt_put()` is unconditional \u2014 every successful route resolution leaks, with no race to win and no memory-layout dependency, and the attacker fully controls `daddr` via the GID it advertises. In an SMC-Rv2 deployment (the scenario in which this code runs at all) the attacker just opens TCP connections in a loop to accumulate leaked references.\nPR:N - `smc_listen_work()` processes the CLC Proposal immediately after TCP accept, before any credential check exists \u2014 SMC has no authentication, and the UEID compared in `smc_clc_match_eid()` is a cleartext fabric identifier the client itself broadcasts in its proposal, not a secret. The client-side path via `smc_connect_rdma_v2_prepare()` requires no EID from the attacker at all.\nUI:N - The attacker initiates the TCP connection to a victim SMC listener and drives the entire handshake itself; the listen worker runs asynchronously with no action by any local user.\nS:U - The leaked `rtable`, `neighbour` and pinned `net_device` references all remain within the kernel\u0027s own resource domain, and no VM/host, IOMMU, or sandbox boundary is crossed.\nC:N - Only reference counts are leaked \u2014 no freed or out-of-bounds memory is read, and nothing from kernel memory is copied back to the peer or to userspace. `nexthop_mac` is filled from a validly-held neighbour before the leak occurs.\nI:N - The bug is a missing decrement, which is the safe direction \u2014 no object is freed early, so there is no UAF, write primitive, or control-flow impact, and both `rcuref` (dst) and `refcount_t` (neigh) saturate with a warning rather than wrapping to zero.\nA:H - Each leaked `dst` and `neighbour` permanently pins a `net_device` reference (`netdev_hold()` in `dst_init()`/`neigh_alloc()`), so device unregistration and network-namespace teardown hang forever in the `unregister_netdevice: waiting for %s to become free` loop, blocking the global `cleanup_net` worker. Additionally, `neigh_forced_gc()` skips any entry with refcount \u003e 1, so an unauthenticated peer varying its advertised GID mints unreclaimable ARP entries until `gc_thresh3` overflow breaks all neighbour resolution on the host, alongside unbounded kernel memory growth."

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: mediatek: Make sure IPI buffer fits in L2TCM
The IPI buffer location is read from the firmware that we load to the
System Companion Processor, and it's not granted that both the SRAM
(L2TCM) size that is defined in the devicetree node is large enough
for that, and while this is especially true for multi-core SCP, it's
still useful to check on single-core variants as well.
Failing to perform this check may make this driver perform R/W
operations out of the L2TCM boundary, resulting (at best) in a
kernel panic.
To fix that, check that the IPI buffer fits, otherwise return a
failure and refuse to boot the relevant SCP core (or the SCP at
all, if this is single core).

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/debugfs: Free all thermal zone debug memory on zone removal
Because thermal_debug_tz_remove() does not free all memory allocated for
thermal zone diagnostics, some of that memory becomes unreachable after
freeing the thermal zone's struct thermal_debugfs object.
Address this by making thermal_debug_tz_remove() free all of the memory
in question.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: timer: Set lower bound of start tick time
Currently ALSA timer doesn't have the lower limit of the start tick
time, and it allows a very small size, e.g. 1 tick with 1ns resolution
for hrtimer. Such a situation may lead to an unexpected RCU stall,
where the callback repeatedly queuing the expire update, as reported
by fuzzer.
This patch introduces a sanity check of the timer start tick time, so
that the system returns an error when a too small start size is set.
As of this patch, the lower limit is hard-coded to 100us, which is
small enough but can still work somehow.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: timer: Set lower bound of start tick time\n\nCurrently ALSA timer doesn\u0027t have the lower limit of the start tick\ntime, and it allows a very small size, e.g. 1 tick with 1ns resolution\nfor hrtimer. Such a situation may lead to an unexpected RCU stall,\nwhere the callback repeatedly queuing the expire update, as reported\nby fuzzer.\n\nThis patch introduces a sanity check of the timer start tick time, so\nthat the system returns an error when a too small start size is set.\nAs of this patch, the lower limit is hard-coded to 100us, which is\nsmall enough but can still work somehow."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix memleak in seg6_hmac_init_algo
seg6_hmac_init_algo returns without cleaning up the previous allocations
if one fails, so it's going to leak all that memory and the crypto tfms.
Update seg6_hmac_exit to only free the memory when allocated, so we can
reuse the code directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix possible use-after-free during activity update
The rule activity update delayed work periodically traverses the list of
configured rules and queries their activity from the device.
As part of this task it accesses the entry pointed by 'ventry->entry',
but this entry can be changed concurrently by the rehash delayed work,
leading to a use-after-free [1].
Fix by closing the race and perform the activity query under the
'vregion->lock' mutex.

No network-facing parser or protocol handler is on the path.\nAC:L - The attacker controls both sides of the race \u2014 rule add/delete churn resets the rehash context and keeps `mlxsw_sp_acl_tcam_ventry_migrate()` continuously freeing entries (credit budget of 100 forces immediate reschedule), while the unlocked activity walker re-scans every rule once per second with a slow per-rule firmware query, giving a wide window that repeats indefinitely. The bug reproduced in real deployments, and the rehash interval is additionally attacker-tunable via the `acl_region_rehash_interval` devlink param.\nPR:L - Installing offloaded flower rules requires CAP_NET_ADMIN in the netns owning the mlxsw netdev, which per kernel CNA convention is scored as low privilege; mlxsw ports are routinely delegated into network namespaces in containerized switch OSes, where a non-root user holding CAP_NET_ADMIN in that namespace can install the filters.\nUI:N - The attacker triggers everything themselves by configuring tc flower rules; the two racing kernel delayed works then fire automatically on their own timers with no victim action required.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free on a general kmalloc-cache object that is pointer-chased (`entry-\u003echunk-\u003eregion-\u003epriv`, `entry-\u003eact_block`) lets an attacker who reclaims the slab redirect reads to arbitrary kernel addresses, yielding an arbitrary-read primitive and disclosure of kernel memory and pointers.\nI:H - The freed object feeds `mlxsw_afa_block_activity_get()`, which performs an indirect call via `block-\u003eafa-\u003eops-\u003ekvdl_set_activity_get` \u2014 three pointer levels all sourced from the freed allocation \u2014 so heap spraying the reclaimed slab gives control-flow hijack and hence arbitrary kernel modification.\nA:H - Even unweaponized, the use-after-free dereferences stale pointers from a kernel workqueue context, producing an oops/panic (as captured in the KASAN report) and taking down the switch\u0027s control plane."

Summary
In the Linux kernel, the following vulnerability has been resolved:
eeprom: at24: fix memory corruption race condition
If the eeprom is not accessible, an nvmem device will be registered, the
read will fail, and the device will be torn down. If another driver
accesses the nvmem device after the teardown, it will reference
invalid memory.
Move the failure point before registering the nvmem device.

There is no network exposure, and the exploitation interface is a local syscall rather than physical manipulation.\nAC:H - Exploitation requires the EEPROM\u0027s one-byte probe read to fail (an I2C/hardware condition a local unprivileged attacker cannot induce) while an nvmem consumer holds a reference across the devres teardown. The consumer half is deterministic on affected platforms (e.g. the NVMEM_ADD notifier in cp500.c fires inside nvmem_register itself), but the hardware-failure half is outside attacker control.\nPR:L - SPD and VAIO at24 chip data clear `root_only`, giving the nvmem and compat eeprom sysfs attributes mode 0444, so any unprivileged local account can invoke the freed `at24_read()` path with no capabilities, namespace tricks, or group membership.\nUI:N - No victim action is needed; the attacker simply reads the sysfs attribute, or an in-kernel consumer touches the stale nvmem device on its own.\nS:U - The use-after-free occurs in kernel memory and its impact is confined to the kernel\u0027s own security authority \u2014 no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reading the stale nvmem device dereferences a freed `at24_data`, and `at24_translate_offset()` indexes `client_regmaps[]` using an index bounded only by the freed `byte_len`, yielding out-of-bounds pointer fetches and regmap reads that return arbitrary reclaimed kernel memory into the user-visible read buffer.\nI:H - `at24_read()` calls `at24-\u003eread_post()` \u2014 a function pointer loaded from freed memory \u2014 and drives regmap op/lock tables out of a freed regmap, while `at24_write()` on a writable instance pushes attacker data through the same stale structures; heap grooming turns this into arbitrary write and control-flow hijack.\nA:H - Even without grooming, the use-after-free dereferences freed regmap and device pointers and locks a freed mutex, reliably producing an oops or panic, and the dangling nvmem device persists so the crash can be triggered repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mst: fix vlan use-after-free
syzbot reported a suspicious rcu usage[1] in bridge's mst code. While
fixing it I noticed that nothing prevents a vlan to be freed while
walking the list from the same path (br forward delay timer). Fix the rcu
usage and also make sure we are not accessing freed memory by making
br_mst_vlan_set_state use rcu read lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: turn folio_test_hugetlb into a PageType
The current folio_test_hugetlb() can be fooled by a concurrent folio split
into returning true for a folio which has never belonged to hugetlbfs.
This can't happen if the caller holds a refcount on it, but we have a few
places (memory-failure, compaction, procfs) which do not and should not
take a speculative reference.
Since hugetlb pages do not use individual page mapcounts (they are always
fully mapped and use the entire_mapcount field to record the number of
mappings), the PageType field is available now that page_mapcount()
ignores the value in this field.
In compaction and with CONFIG_DEBUG_VM enabled, the current implementation
can result in an oops, as reported by Luis. This happens since 9c5ccf2db04b
("mm: remove HUGETLB_PAGE_DTOR") effectively added some VM_BUG_ON() checks
in the PageHuge() testing path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix verifier assumptions about socket->sk
The verifier assumes that 'sk' field in 'struct socket' is valid
and non-NULL when 'socket' pointer itself is trusted and non-NULL.
That may not be the case when socket was just created and
passed to LSM socket_accept hook.
Fix this verifier assumption and adjust tests.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix kernel crash when devlink reload during initialization
The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel
crash.
This patch fixes this by registering the devlink after
hardware initialization.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: Check for port partner validity before consuming it
typec_register_partner() does not guarantee partner registration
to always succeed. In the event of failure, port->partner is set
to the error value or NULL. Given that port->partner validity is
not checked, this results in the following crash:
Unable to handle kernel NULL pointer dereference at virtual address xx
pc : run_state_machine+0x1bc8/0x1c08
lr : run_state_machine+0x1b90/0x1c08
..
Call trace:
run_state_machine+0x1bc8/0x1c08
tcpm_state_machine_work+0x94/0xe4
kthread_worker_fn+0x118/0x328
kthread+0x1d0/0x23c
ret_from_fork+0x10/0x20
To prevent the crash, check for port->partner validity before
derefencing it in all the call sites.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Add 0 size check to mtk_drm_gem_obj
Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object
of 0 bytes. Currently, no such check exists and the kernel will panic if
a userspace application attempts to allocate a 0x0 GBM buffer.
Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and
verifying that we now return EINVAL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: ensure the copied buf is NUL terminated
Currently, we allocate a count-sized kernel buffer and copy count bytes
from userspace to that buffer. Later, we use sscanf on this buffer but we
don't ensure that the string is terminated inside the buffer, this can lead
to OOB read when using sscanf. Fix this issue by using memdup_user_nul
instead of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bcmasp: fix memory leak when bringing down interface
When bringing down the TX rings we flush the rings but forget to
reclaimed the flushed packets. This leads to a memory leak since we
do not free the dma mapped buffers. This also leads to tx control
block corruption when bringing down the interface for power
management.

No received packet or remote protocol interaction can drive interface teardown, so this requires local system access.\nAC:L - The triggering party controls both halves \u2014 flooding fragmented TX traffic guarantees in-flight descriptors at teardown, and the tiny `DESC_RING_COUNT` ring wraps into the stale `tx_cbs` region within milliseconds of resuming, so the premature `dev_consume_skb_any()` and subsequent double free are deterministic and repeatable. No unpredictable memory layout or victim state is required.\nPR:L - On the BRCMSTB set-top/embedded systems this driver targets, the suspend-to-WoL standby cycle that produces the `tx_cbs` corruption is an automatic system event, not an attacker privilege; an unprivileged local process only needs to be generating fragmented TX traffic when it occurs. Choosing the higher-severity option between low privilege and root, since the corruption path does not itself depend on CAP_NET_ADMIN.\nUI:N - Idle/autosleep standby entry and admin-scripted interface cycling (NetworkManager, DHCP renewal, WoL standby) occur with no victim action. The leak accrues on every interface-down with no interaction at all.\nS:U - The leaked memory, freed skbs, and corrupted slab freelist all live within the kernel\u0027s own security authority. There is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The stale `last` flag frees an skb (releasing its fragment page references) while later descriptors for that same skb are still pending in the hardware ring and still DMA-mapped, so reallocated pages holding other processes\u0027 data can be DMA\u0027d out onto the wire. The resulting `skbuff_head_cache` double free additionally yields overlapping allocations usable as a kernel read primitive.\nI:H - Freeing the same skb twice corrupts the SLUB freelist, allowing two live objects to alias the same memory \u2014 the standard route to a controlled kernel write and control-flow hijack. Skipped `dma_unmap_single()` also leaves the device with live mappings into memory that has been returned to the allocator.\nA:H - The double free trips SLUB\u0027s detection (BUG/panic) or silently corrupts the allocator into a later oops. Independently, the unreclaimed skbs and DMA mappings leak on every interface-down, exhausting memory and SWIOTLB/IOVA space over repeated up/down or standby cycles."

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid dirent corruption
As Al reported in link[1]:
f2fs_rename()
...
if (old_dir != new_dir && !whiteout)
f2fs_set_link(old_inode, old_dir_entry,
old_dir_page, new_dir);
else
f2fs_put_page(old_dir_page, 0);
You want correct inumber in the ".." link. And cross-directory
rename does move the source to new parent, even if you'd been asked
to leave a whiteout in the old place.
[1] https://lore.kernel.org/all/20231017055040.GN800259@ZenIV/
With below testcase, it may cause dirent corruption, due to it missed
to call f2fs_set_link() to update ".." link to new directory.
- mkdir -p dir/foo
- renameat2 -w dir/foo bar
[ASSERT] (__chk_dots_dentries:1421) --> Bad inode number[0x4] for '..', parent parent ino is [0x3]
[FSCK] other corrupted bugs [Fail]

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: max3100: Lock port->lock when calling uart_handle_cts_change()
uart_handle_cts_change() has to be called with port lock taken,
Since we run it in a separate work, the lock may not be taken at
the time of running. Make sure that it's taken by explicitly doing
that. Without it we got a splat:
WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0
...
Workqueue: max3100-0 max3100_work [max3100]

Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails
In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.
VMBus code could free decrypted pages if set_memory_encrypted()/decrypted()
fails. Leak the pages if this happens.

This matches the established scoring for CoCo host-to-guest issues in this subsystem (CVE-2024-57793).\nAC:L - The VMM implements the page-state-change handler invoked by `enc_status_change_prepare`/`_finish` and can deterministically fail it every time, forcing `set_memory_decrypted()`/`set_memory_encrypted()` to return an error on demand. No race, timing, or memory-layout condition outside the attacker\u0027s control is involved.\nPR:N - `vmbus_connect()` runs from `vmbus_bus_init()` during guest boot and `vmbus_disconnect()` from module unload/kexec, so the host needs no account, credential, or capability inside the guest at all. The hypervisor sits entirely outside the guest\u0027s authentication domain in the SEV-SNP/TDX threat model.\nUI:N - The vulnerable path executes automatically when the hv_vmbus driver initializes at guest boot; the host triggers the failed conversion itself and no guest user or administrator has to perform any action.\nS:C - Returning still-shared pages to the buddy allocator breaks the hardware-enforced SEV-SNP/TDX confidential-computing boundary, so data belonging to every other authority in the guest (all processes, containers, and the guest\u0027s protected TCB) becomes host-accessible \u2014 impact far beyond the VMBus driver\u0027s own scope, directly analogous to an IOMMU/DMA boundary bypass.\nC:H - The recycled monitor pages remain mapped shared by the host, so anything the guest later places in them \u2014 slab objects, page cache, anonymous user data, cryptographic keys \u2014 is exposed in plaintext, giving a persistent, continuously refreshed arbitrary-read window into confidential guest memory.\nI:H - The host can write those pages at will while they hold live kernel or user data, yielding an arbitrary-write primitive into whatever object currently occupies them (kernel structures with function pointers or list heads), which is leverageable for control-flow hijack inside the guest.\nA:H - Host modification of live kernel objects in the recycled pages, together with the private/shared state mismatch left by the aborted conversion (#VE / EPT violation on subsequent guest kernel accesses), reliably produces guest memory corruption and kernel panic."

drm/vmwgfx: Fix invalid reads in fence signaled events
Correctly set the length of the drm_event to the size of the structure
that's actually used.
The length of the drm_event was set to the parent structure instead of
to the drm_vmw_event_fence which is supposed to be read. drm_read
uses the length parameter to copy the event to the user space thus
resuling in oob reads.

There is no network-facing path to this code.\nAC:L - Exploitation is fully deterministic \u2014 a single ioctl followed by a read reliably copies 72 bytes past the end of the allocation, with no race, no timing window, and no attacker-uncontrolled precondition. Heap grooming of the kmalloc-96 cache to control the leaked neighbour is standard and repeatable at will.\nPR:L - The ioctl is marked DRM_RENDER_ALLOW, so it is served on the render node which is world-accessible (0666 or group \"render\") on typical VMware guest desktop/workstation installs \u2014 no DRM master, DRM_AUTH, or capability check is applied. Any unprivileged local user with a graphics session or render-node access can reach it.\nUI:N - The attacker opens its own DRM fd, issues the ioctl and reads the event entirely within its own process. No victim action or interaction of any kind is required.\nS:U - The leaked data is guest kernel heap memory disclosed to guest userspace, and any resulting crash is confined to the same kernel. The vulnerable component and the impacted resources share one security authority; there is no guest-to-host or IOMMU boundary crossing.\nC:H - 72 bytes of adjacent kernel slab memory are copied verbatim to userspace on every event read, and the attacker can groom the kmalloc-96 cache and repeat the read indefinitely to harvest kernel pointers, SLUB freelist values and residual object contents. This is a substantial, repeatable kernel heap information disclosure enabling KASLR/heap-address defeat, not a strictly bounded few-byte read.\nI:N - The defect is purely an over-long read; no data is written out of bounds and the inflated length is applied symmetrically to the event_space reserve/release accounting, so no kernel state is corrupted. There is no write or control-flow primitive.\nA:H - On the many distro and Android kernels built with CONFIG_HARDENED_USERCOPY=y, __check_heap_object() rejects the 96-byte copy starting at offset 72 of a 96-byte object and calls usercopy_abort(), which invokes BUG() \u2014 an unprivileged local user can therefore force a kernel oops (or full panic with panic_on_oops) on demand."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
l2cap_le_flowctl_init() can cause both div-by-zero and an integer
overflow since hdev->le_mtu may not fall in the valid range.
Move MTU from hci_dev to hci_conn to validate MTU and stop the connection
process earlier if MTU is invalid.
Also, add a missing validation in read_buffer_size() and make it return
an error value if the validation fails.
Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a
kzalloc failure and invalid MTU value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: qca: fix NULL-deref on non-serdev suspend
Qualcomm ROME controllers can be registered from the Bluetooth line
discipline and in this case the HCI UART serdev pointer is NULL.
Add the missing sanity check to prevent a NULL-pointer dereference when
wakeup() is called for a non-serdev controller during suspend.
Just return true for now to restore the original behaviour and address
the crash with pre-6.2 kernels, which do not have commit e9b3e5b8c657
("Bluetooth: hci_qca: only assign wakeup with serial port support") that
causes the crash to happen already at setup() time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: Fix use after free in lineinfo_changed_notify
The use-after-free issue occurs as follows: when the GPIO chip device file
is being closed by invoking gpio_chrdev_release(), watched_lines is freed
by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier
chain failed due to waiting write rwsem. Additionally, one of the GPIO
chip's lines is also in the release process and holds the notifier chain's
read rwsem. Consequently, a race condition leads to the use-after-free of
watched_lines.
Here is the typical stack when issue happened:
[free]

--> lineinfo_changed_notify()
--> test_bit(xxxx, cdev->watched_lines) <-- use after free
The side effect of the use-after-free issue is that a GPIO line event is
being generated for userspace where it shouldn't. However, since the chrdev
is being closed, userspace won't have the chance to read that event anyway.
To fix the issue, call the bitmap_free() function after the unregistration
of lineinfo_changed_nb notifier chain.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soundwire: cadence: fix invalid PDI offset
For some reason, we add an offset to the PDI, presumably to skip the
PDI0 and PDI1 which are reserved for BPT.
This code is however completely wrong and leads to an out-of-bounds
access. We were just lucky so far since we used only a couple of PDIs
and remained within the PDI array bounds.
A Fixes: tag is not provided since there are no known platforms where
the out-of-bounds would be accessed, and the initial code had problems
as well.
A follow-up patch completely removes this useless offset.

{
"lang": "en",
"value": "AV:L - The vulnerable code is reached only through the ALSA PCM device node (`/dev/snd/pcmC*D*`) via `SNDRV_PCM_IOCTL_HW_PARAMS`, which funnels into the ASoC DAI `.hw_params` callback `intel_hw_params()` and then `sdw_cdns_alloc_pdi()`. This requires local access to the machine; there is no network or adjacent-network path to a SoundWire manager DAI.\nAC:L - The out-of-bounds walk is unconditional arithmetic (`i = 2; i \u003c 2 + num_bd`) with no race, no timing window, and no dependency on memory layout to occur \u2014 an attacker simply configures hw_params on a bidirectional-PDI DAI and the read past the array happens deterministically. Heap grooming to make the adjacent slab object\u0027s first word match the small `dai_id` value, and thus convert the read into the OOB write, is standard and repeatable since the attacker can retry the ioctl arbitrarily many times.\nPR:L - The attacker needs no capabilities, only the ability to open a PCM device \u2014 granted to ordinary desktop users via the `audio` group or logind seat ACLs, and to ordinary apps in Android\u0027s audio domain. No CAP_SYS_ADMIN, CAP_SYS_RAWIO, or root check exists anywhere on the path from the ioctl to `cdns_find_pdi()`.\nUI:N - The attacker performs the entire sequence itself \u2014 open the PCM device and issue HW_PARAMS with a chosen channel count \u2014 with no victim action, no filesystem mount, and no file opened by another user.\nS:U - The out-of-bounds read and write both occur in kernel heap memory within the same kernel security authority; nothing crosses a VM, IOMMU, or sandbox boundary.\nC:H - The loop reads `pdi[num_bd].num` and `pdi[num_bd+1].num` from beyond the `devm_kcalloc()` allocation, and the resulting out-of-bounds pointer is stored in `dai_runtime-\u003epdi` and used to source values (`num`, `intel_alh_id`, `ch_count`) that are programmed into SHIM/ALH/Cadence registers, leaking adjacent kernel heap contents; per kernel guidance, heap memory corruption of this kind is leverageable for information disclosure.\nI:H - When the out-of-bounds `num` matches `dai_id`, `sdw_cdns_alloc_pdi()` writes five fields (`l_ch_num`, `h_ch_num`, `ch_count`, `dir`, and later `intel_alh_id`) through the out-of-bounds pointer, corrupting roughly 20 bytes of the neighbouring slab object with values partly controlled by the attacker-supplied channel count. A heap out-of-bounds write with attacker-influenced data is a classic primitive for control-flow hijack via heap grooming.\nA:H - The out-of-bounds access trips KASAN/hardened-usercopy checks and, on production kernels, corrupts adjacent slab metadata or a neighbouring object, readily producing an oops or panic; the stale out-of-bounds `dai_runtime-\u003epdi` pointer is re-dereferenced in `.prepare`, `.trigger`, and `.hw_free`, compounding the crash potential."

This is the standard Bluetooth adjacent-network attack surface, not a local syscall interface.\nAC:L - The attacker fully controls the trigger (coredump packet stream) and can repeat it without limit, and the driver\u0027s own btmtk_reset_sync()/re-setup cycle after each coredump regenerates the window in which hci_devcd_append() takes its skb-consuming error path. An attack that can simply be retried until it lands is Low complexity under CVSS 3.1.\nPR:N - No credentials or privileges on the target host are required \u2014 the path is driven by controller RX data with no capability check, and the over-the-air frames that assert MediaTek BT firmware are processed at baseband/LMP level before any pairing or authentication.\nUI:N - No victim action is needed; the packets are consumed automatically by the btusb URB completion handler on any system with Bluetooth enabled.\nS:U - The double free corrupts kernel slab memory and its impact is confined to the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - A double free of an sk_buff yields a use-after-free on a reallocated slab object, letting the attacker groom the freed slot and read back kernel memory contents through the still-referenced structure.\nI:H - The second kfree_skb() decrements a refcount inside freed memory and re-frees a slot that may already hold a live object, giving a heap-corruption/arbitrary-write primitive exploitable for control-flow hijacking.\nA:H - Double frees trigger immediate slab corruption, refcount underflow warnings, and kernel panics (BUG on freelist corruption) even when not weaponized, and the attacker can repeat the firmware crash to force it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix potential uninit-value access in __ip6_make_skb()
As it was done in commit fc1092f51567 ("ipv4: Fix uninit-value access in
__ip_make_skb()") for IPv4, check FLOWI_FLAG_KNOWN_NH on fl6->flowi6_flags
instead of testing HDRINCL on the socket to avoid a race condition which
causes uninit-value access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()
Extend a critical section to prevent chan from early freeing.
Also make the l2cap_connect() return type void. Nothing is using the
returned value but it is ugly to return a potentially freed pointer.
Making it void will help with backports because earlier kernels did use
the return value. Now the compile will break for kernels where this
patch is not a complete fix.
Call stack summary:

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: h6: Reparent CPUX during PLL CPUX rate change
While PLL CPUX clock rate change when CPU is running from it works in
vast majority of cases, now and then it causes instability. This leads
to system crashes and other undefined behaviour. After a lot of testing
(30+ hours) while also doing a lot of frequency switches, we can't
observe any instability issues anymore when doing reparenting to stable
clock like 24 MHz oscillator.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix memory leak when canceling rehash work
The rehash delayed work is rescheduled with a delay if the number of
credits at end of the work is not negative as supposedly it means that
the migration ended. Otherwise, it is rescheduled immediately.
After "mlxsw: spectrum_acl_tcam: Fix possible use-after-free during
rehash" the above is no longer accurate as a non-negative number of
credits is no longer indicative of the migration being done. It can also
happen if the work encountered an error in which case the migration will
resume the next time the work is scheduled.
The significance of the above is that it is possible for the work to be
pending and associated with hints that were allocated when the migration
started. This leads to the hints being leaked [1] when the work is
canceled while pending as part of ACL region dismantle.
Fix by freeing the hints if hints are associated with a work that was
canceled while pending.
Blame the original commit since the reliance on not having a pending
work associated with hints is fragile.

This leads to the hints being leaked [1] when the work is\ncanceled while pending as part of ACL region dismantle.\n\nFix by freeing the hints if hints are associated with a work that was\ncanceled while pending.\n\nBlame the original commit since the reliance on not having a pending\nwork associated with hints is fragile.\n\n[1]\nunreferenced object 0xffff88810e7c3000 (size 256):\n comm \"kworker/0:16\", pid 176, jiffies 4295460353\n hex dump (first 32 bytes):\n 00 30 95 11 81 88 ff ff 61 00 00 00 00 00 00 80 .0......a.......\n 00 00 61 00 40 00 00 00 00 00 00 00 04 00 00 00 ..a.@...........\n backtrace (crc 2544ddb9):\n [\u003c00000000cf8cfab3\u003e] kmalloc_trace+0x23f/0x2a0\n [\u003c000000004d9a1ad9\u003e] objagg_hints_get+0x42/0x390\n [\u003c000000000b143cf3\u003e] mlxsw_sp_acl_erp_rehash_hints_get+0xca/0x400\n [\u003c0000000059bdb60a\u003e] mlxsw_sp_acl_tcam_vregion_rehash_work+0x868/0x1160\n [\u003c00000000e81fd734\u003e] process_one_work+0x59c/0xf20\n [\u003c00000000ceee9e81\u003e] worker_thread+0x799/0x12c0\n [\u003c00000000bda6fe39\u003e] kthread+0x246/0x300\n [\u003c0000000070056d23\u003e] ret_from_fork+0x34/0x70\n [\u003c00000000dea2b93e\u003e] ret_from_fork_asm+0x1a/0x30"

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map()
If we fail to allocate propname buffer, we need to drop the reference
count we just took. Because the pinctrl_dt_free_maps() includes the
droping operation, here we call it directly.

9f74a3dfcf83 ("ice: Fix VF Reset paths when interface in a failed over
aggregate"), the ice driver has acquired the LAG mutex in ice_reset_vf().
The commit placed this lock acquisition just prior to the acquisition of
the VF configuration lock.
If ice_reset_vf() acquires the configuration lock via the ICE_VF_RESET_LOCK
flag, this could deadlock with ice_vc_cfg_qs_msg() because it always
acquires the locks in the order of the VF configuration lock and then the
LAG mutex.
Lockdep reports this violation almost immediately on creating and then
removing 2 VF:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Atom Integrated System Info v2_2 for DCN35
New request from KMD/VBIOS in order to support new UMA carveout
model. This fixes a null dereference from accessing
Ctx->dc_bios->integrated_info while it was NULL.
DAL parses through the BIOS and extracts the necessary
integrated_info but was missing a case for the new BIOS
version 2.3.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
TCP_SYN_RECV state is really special, it is only used by
cross-syn connections, mostly used by fuzzers.
In the following crash [1], syzbot managed to trigger a divide
by zero in tcp_rcv_space_adjust()
A socket makes the following state transitions,
without ever calling tcp_init_transfer(),
meaning tcp_init_buffer_space() is also not called.
TCP_CLOSE
connect()
TCP_SYN_SENT
TCP_SYN_RECV
shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)
TCP_FIN_WAIT1
To fix this issue, change tcp_shutdown() to not
perform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,
which makes no sense anyway.
When tcp_rcv_state_process() later changes socket state
from TCP_SYN_RECV to TCP_ESTABLISH, then look at
sk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,
and send a FIN packet from a sane socket state.
This means tcp_send_fin() can now be called from BH
context, and must use GFP_ATOMIC allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: n_gsm: fix possible out-of-bounds in gsm0_receive()
Assuming the following:
- side A configures the n_gsm in basic option mode
- side B sends the header of a basic option mode frame with data length 1
- side A switches to advanced option mode
- side B sends 2 data bytes which exceeds gsm->len
Reason: gsm->len is not used in advanced option mode.
- side A switches to basic option mode
- side B keeps sending until gsm0_receive() writes past gsm->buf
Reason: Neither gsm->state nor gsm->len have been reset after
reconfiguration.
Fix this by changing gsm->count to gsm->len comparison from equal to less
than. Also add upper limit checks against the constant MAX_MRU in
gsm0_receive() and gsm1_receive() to harden against memory corruption of
gsm->len and gsm->mru.
All other checks remain as we still need to limit the data according to the
user configuration and actual payload size.

No network or physical access is involved.\nAC:L - The attacker controls both sides of the pty pair, so the exact sequence (fill count in advanced mode, reconfigure to basic mode, keep writing) is deterministic and requires no race or unpredictable memory state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tun: limit printing rate when illegal packet received by tun dev
vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.
net_ratelimit mechanism can be used to limit the dumping rate.

[ 2057.572847] Kernel panic - not syncing: Fatal exception in interrupt
-------------------------------------------------------------------------------------------
Analysis:
There is one napi structure per out_q: card->qdio.out_qs[i].napi
The napi.poll functions are set during qeth_open().
Since
commit 1cfef80d4c2b ("s390/qeth: Don't call dev_close/dev_open (DOWN/UP)")
qeth_set_offline()/qeth_set_online() no longer call dev_close()/
dev_open(). So if qeth_free_qdio_queues() cleared
card->qdio.out_qs[i].napi.poll while the network interface was UP and the
card was offline, they are not set again.
Reproduction:
chzdev -e $devno layer2=0
ip link set dev $network_interface up
echo 0 > /sys/bus/ccw

Summary
In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix a race between readers and resize checks
The reader code in rb_get_reader_page() swaps a new reader page into the
ring buffer by doing cmpxchg on old->list.prev->next to point it to the
new page. Following that, if the operation is successful,
old->list.next->prev gets updated too. This means the underlying
doubly-linked list is temporarily inconsistent, page->prev->next or
page->next->prev might not be equal back to page for some page in the
ring buffer.
The resize operation in ring_buffer_resize() can be invoked in parallel.
It calls rb_check_pages() which can detect the described inconsistency
and stop further tracing:

Note that ring_buffer_resize() calls rb_check_pages() only if the parent
trace_buffer has recording disabled. Recent commit d78ab792705c
("tracing: Stop current tracer when resizing buffer") causes that it is
now always the case which makes it more likely to experience this issue.
The window to hit this race is nonetheless very small. To help
reproducing it, one can add a delay loop in rb_get_reader_page():
ret = rb_head_page_replace(reader, cpu_buffer->reader_page);
if (!ret)
goto spin;
for (unsigned i = 0; i < 1U << 26; i++) /* inserted delay loop */
__asm__ __volatile__ ("" : : : "memory");
rb_list_head(reader->list.next)->prev = &cpu_buffer->reader_page->list;

This means the underlying\ndoubly-linked list is temporarily inconsistent, page-\u003eprev-\u003enext or\npage-\u003enext-\u003eprev might not be equal back to page for some page in the\nring buffer.\n\nThe resize operation in ring_buffer_resize() can be invoked in parallel.\nIt calls rb_check_pages() which can detect the described inconsistency\nand stop further tracing:\n\n[ 190.271762] ------------[ cut here ]------------\n[ 190.271771] WARNING: CPU: 1 PID: 6186 at kernel/trace/ring_buffer.c:1467 rb_check_pages.isra.0+0x6a/0xa0\n[ 190.271789] Modules linked in: [...]\n[ 190.271991] Unloaded tainted modules: intel_uncore_frequency(E):1 skx_edac(E):1\n[ 190.272002] CPU: 1 PID: 6186 Comm: cmd.sh Kdump: loaded Tainted: G E 6.9.0-rc6-default #5 158d3e1e6d0b091c34c3b96bfd99a1c58306d79f\n[ 190.272011] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.0-0-gd239552c-rebuilt.opensuse.org 04/01/2014\n[ 190.272015] RIP: 0010:rb_check_pages.isra.0+0x6a/0xa0\n[ 190.272023] Code: [...]\n[ 190.272028] RSP: 0018:ffff9c37463abb70 EFLAGS: 00010206\n[ 190.272034] RAX: ffff8eba04b6cb80 RBX: 0000000000000007 RCX: ffff8eba01f13d80\n[ 190.272038] RDX: ffff8eba01f130c0 RSI: ffff8eba04b6cd00 RDI: ffff8eba0004c700\n[ 190.272042] RBP: ffff8eba0004c700 R08: 0000000000010002 R09: 0000000000000000\n[ 190.272045] R10: 00000000ffff7f52 R11: ffff8eba7f600000 R12: ffff8eba0004c720\n[ 190.272049] R13: ffff8eba00223a00 R14: 0000000000000008 R15: ffff8eba067a8000\n[ 190.272053] FS: 00007f1bd64752c0(0000) GS:ffff8eba7f680000(0000) knlGS:0000000000000000\n[ 190.272057] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 190.272061] CR2: 00007f1bd6662590 CR3: 000000010291e001 CR4: 0000000000370ef0\n[ 190.272070] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[ 190.272073] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[ 190.272077] Call Trace:\n[ 190.272098] \u003cTASK\u003e\n[ 190.272189] ring_buffer_resize+0x2ab/0x460\n[ 190.272199] __tracing_resize_ring_buffer.part.0+0x23/0xa0\n[ 190.272206] tracing_resize_ring_buffer+0x65/0x90\n[ 190.272216] tracing_entries_write+0x74/0xc0\n[ 190.272225] vfs_write+0xf5/0x420\n[ 190.272248] ksys_write+0x67/0xe0\n[ 190.272256] do_syscall_64+0x82/0x170\n[ 190.272363] entry_SYSCALL_64_after_hwframe+0x76/0x7e\n[ 190.272373] RIP: 0033:0x7f1bd657d263\n[ 190.272381] Code: [...]\n[ 190.272385] RSP: 002b:00007ffe72b643f8 EFLAGS: 00000246 ORIG_RAX: 0000000000000001\n[ 190.272391] RAX: ffffffffffffffda RBX: 0000000000000002 RCX: 00007f1bd657d263\n[ 190.272395] RDX: 0000000000000002 RSI: 0000555a6eb538e0 RDI: 0000000000000001\n[ 190.272398] RBP: 0000555a6eb538e0 R08: 000000000000000a R09: 0000000000000000\n[ 190.272401] R10: 0000555a6eb55190 R11: 0000000000000246 R12: 00007f1bd6662500\n[ 190.272404] R13: 0000000000000002 R14: 00007f1bd6667c00 R15: 0000000000000002\n[ 190.272412] \u003c/TASK\u003e\n[ 190.272414] ---[ end trace 0000000000000000 ]---\n\nNote that ring_buffer_resize() calls rb_check_pages() only if the parent\ntrace_buffer has recording disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix mb_cache_entry's e_refcnt leak in ext4_xattr_block_cache_find()
Syzbot reports a warning as follows:
============================================
WARNING: CPU: 0 PID: 5075 at fs/mbcache.c:419 mb_cache_destroy+0x224/0x290
Modules linked in:
CPU: 0 PID: 5075 Comm: syz-executor199 Not tainted 6.9.0-rc6-gb947cc5bf6d7
RIP: 0010:mb_cache_destroy+0x224/0x290 fs/mbcache.c:419
Call Trace:
<TASK>
ext4_put_super+0x6d4/0xcd0 fs/ext4/super.c:1375
generic_shutdown_super+0x136/0x2d0 fs/super.c:641
kill_block_super+0x44/0x90 fs/super.c:1675
ext4_kill_sb+0x68/0xa0 fs/ext4/super.c:7327
[...]
============================================
This is because when finding an entry in ext4_xattr_block_cache_find(), if
ext4_sb_bread() returns -ENOMEM, the ce's e_refcnt, which has already grown
in the __entry_find(), won't be put away, and eventually trigger the above
issue in mb_cache_destroy() due to reference count leakage.
So call mb_cache_entry_put() on the -ENOMEM error branch as a quick fix.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak
Using completion_done to determine whether the caller has gone
away only works after a complete call. Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bna: ensure the copied buf is NUL terminated
Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul
instead of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xdp: use flags field to disambiguate broadcast redirect
When redirecting a packet using XDP, the bpf_redirect_map() helper will set
up the redirect destination information in struct bpf_redirect_info (using
the __bpf_xdp_redirect_map() helper function), and the xdp_do_redirect()
function will read this information after the XDP program returns and pass
the frame on to the right redirect destination.
When using the BPF_F_BROADCAST flag to do multicast redirect to a whole
map, __bpf_xdp_redirect_map() sets the 'map' pointer in struct
bpf_redirect_info to point to the destination map to be broadcast. And
xdp_do_redirect() reacts to the value of this map pointer to decide whether
it's dealing with a broadcast or a single-value redirect. However, if the
destination map is being destroyed before xdp_do_redirect() is called, the
map pointer will be cleared out (by bpf_clear_redirect_map()) without
waiting for any XDP programs to stop running. This causes xdp_do_redirect()
to think that the redirect was to a single target, but the target pointer
is also NULL (since broadcast redirects don't have a single target), so
this causes a crash when a NULL pointer is passed to dev_map_enqueue().
To fix this, change xdp_do_redirect() to react directly to the presence of
the BPF_F_BROADCAST flag in the 'flags' value in struct bpf_redirect_info
to disambiguate between a single-target and a broadcast redirect. And only
read the 'map' pointer if the broadcast flag is set, aborting if that has
been cleared out in the meantime. This prevents the crash, while keeping
the atomic (cmpxchg-based) clearing of the map pointer itself, and without
adding any more checks in the non-broadcast fast path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bcache: fix variable length array abuse in btree_iter
btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.
This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length
data array.

"value": "AV:L - The vulnerable code is the bcache btree-node read path, reached only through local block I/O to a bcache device (`cached_dev_submit_bio` \u2192 `cache_lookup` \u2192 `bch_btree_node_read_done`) or local registration of a cache device. There is no network-facing consumer of this code.\nAC:L - The out-of-bounds indexing is deterministic, not a race: `iter-\u003esize` is set to `bucket_size/block_size` (1024 with the default 512K/512B geometry) against a declared 4-element array, so every btree node carrying more than MAX_BSETS bsets walks past the array bound. An attacker who supplies the cache device additionally controls the bset count and the bucket/block geometry directly.\nPR:L - No capability check exists on the path \u2014 an unprivileged local user\u0027s ordinary file I/O on a bcache-backed filesystem causes btree cache misses that call `bch_btree_node_get()` \u2192 `bch_btree_node_read_done()` and run the oversized iterator. Root is only needed for the stronger variant where the attacker also supplies a crafted cache superblock.\nUI:N - No victim action is required; the out-of-bounds accesses occur during normal read servicing on an already-configured bcache device. Even the crafted-device variant is auto-triggered by bcache-tools\u0027 udev register rule rather than by any user step.\nS:U - The corruption is confined to kernel slab memory belonging to the bcache cache set, within the same security authority as the kernel itself. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `heap_add`/`heap_sift`/`heap_pop` read and write `btree_iter_set` entries (pairs of `struct bkey *`) far beyond the declared four-element array, and in `CONFIG_BCACHE_DEBUG` builds and with buckets exceeding the `meta_bucket_pages()` cap the mempool object is genuinely undersized, so adjacent slab contents are read back as bkey pointers and dereferenced by `btree_mergesort()`, giving an out-of-bounds read primitive usable for disclosure.\nI:H - This is an out-of-bounds write of attacker-influenced pointer values into adjacent slab objects whenever the allocation is short of `iter-\u003esize`, and the sift/swap operations shuffle those entries arbitrarily. Corrupting neighbouring heap objects with controlled pointers is a classic path to control-flow hijack.\nA:H - Slab corruption from the out-of-bounds heap operations causes oopses, `bch_btree_iter_push()` hits a `BUG_ON` when the heap fills, and on kernels built with UBSAN array-bounds trapping the out-of-range index is a hard trap producing an immediate panic \u2014 all reachable repeatedly through ordinary I/O."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cppc_cpufreq: Fix possible null pointer dereference
cppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from
different places with various parameters. So cpufreq_cpu_get() can return
null as 'policy' in some circumstances.
Fix this bug by adding null return check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

is followed with a dereference of mycs->yuv_scaler_binary after the
following call chain:
sh_css_pipe_load_binaries()
|-> load_video_binaries(mycs->yuv_scaler_binary == NULL)
|
|-> sh_css_pipe_unload_binaries()
|-> unload_video_binaries()
In unload_video_binaries(), it calls to ia_css_binary_unload with argument
&pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the
same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer
dereference is triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
speakup: Fix sizeof() vs ARRAY_SIZE() bug
The "buf" pointer is an array of u16 values. This code should be
using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512),
otherwise it can the still got out of bounds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()
Patch series "mm: follow_pte() improvements and acrn follow_pte() fixes".
Patch #1 fixes a bunch of issues I spotted in the acrn driver. It
compiles, that's all I know. I'll appreciate some review and testing from
acrn folks.
Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding
more sanity checks, and improving the documentation. Gave it a quick test
on x86-64 using VM_PAT that ends up using follow_pte().
This patch (of 3):
We currently miss handling various cases, resulting in a dangerous
follow_pte() (previously follow_pfn()) usage.
(1) We're not checking PTE write permissions.
Maybe we should simply always require pte_write() like we do for
pin_user_pages_fast(FOLL_WRITE)? Hard to tell, so let's check for
ACRN_MEM_ACCESS_WRITE for now.
(2) We're not rejecting refcounted pages.
As we are not using MMU notifiers, messing with refcounted pages is
dangerous and can result in use-after-free. Let's make sure to reject them.
(3) We are only looking at the first PTE of a bigger range.
We only lookup a single PTE, but memmap->len may span a larger area.
Let's loop over all involved PTEs and make sure the PFN range is
actually contiguous. Reject everything else: it couldn't have worked
either way, and rather made use access PFNs we shouldn't be accessing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: Fix deadlocks with kctl removals at disconnection
In snd_card_disconnect(), we set card->shutdown flag at the beginning,
call callbacks and do sync for card->power_ref_sleep waiters at the
end. The callback may delete a kctl element, and this can lead to a
deadlock when the device was in the suspended state. Namely:
* A process waits for the power up at snd_power_ref_and_wait() in
snd_ctl_info() or read/write() inside card->controls_rwsem.
* The system gets disconnected meanwhile, and the driver tries to
delete a kctl via snd_ctl_remove*(); it tries to take
card->controls_rwsem again, but this is already locked by the
above. Since the sleeper isn't woken up, this deadlocks.
An easy fix is to wake up sleepers before processing the driver
disconnect callbacks but right after setting the card->shutdown flag.
Then all sleepers will abort immediately, and the code flows again.
So, basically this patch moves the wait_event() call at the right
timing. While we're at it, just to be sure, call wait_event_all()
instead of wait_event(), although we don't use exclusive events on
this queue for now.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix possible use-after-free during rehash
The rehash delayed work migrates filters from one region to another
according to the number of available credits.
The migrated from region is destroyed at the end of the work if the
number of credits is non-negative as the assumption is that this is
indicative of migration being complete. This assumption is incorrect as
a non-negative number of credits can also be the result of a failed
migration.
The destruction of a region that still has filters referencing it can
result in a use-after-free [1].
Fix by not destroying the region if migration failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Don't free decrypted memory
In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.
The VMBus device UIO driver could free decrypted/shared pages if
set_memory_decrypted() fails. Check the decrypted field in the gpadl
to decide whether to free the memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ks8851: Queue RX packets in IRQ handler instead of disabling BHs
Currently the driver uses local_bh_disable()/local_bh_enable() in its
IRQ handler to avoid triggering net_rx_action() softirq on exit from
netif_rx(). The net_rx_action() could trigger this driver .start_xmit
callback, which is protected by the same lock as the IRQ handler, so
calling the .start_xmit from netif_rx() from the IRQ handler critical
section protected by the lock could lead to an attempt to claim the
already claimed lock, and a hang.
The local_bh_disable()/local_bh_enable() approach works only in case
the IRQ handler is protected by a spinlock, but does not work if the
IRQ handler is protected by mutex, i.e. this works for KS8851 with
Parallel bus interface, but not for KS8851 with SPI bus interface.
Remove the BH manipulation and instead of calling netif_rx() inside
the IRQ handler code protected by the lock, queue all the received
SKBs in the IRQ handler into a queue first, and once the IRQ handler
exits the critical section protected by the lock, dequeue all the
queued SKBs and push them all into netif_rx(). At this point, it is
safe to trigger the net_rx_action() softirq, since the netif_rx()
call is outside of the lock that protects the IRQ handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
macintosh/via-macii: Fix "BUG: sleeping function called from invalid context"
The via-macii ADB driver calls request_irq() after disabling hard
interrupts. But disabling interrupts isn't necessary here because the
VIA shift register interrupt was masked during VIA1 initialization.

Summary
In the Linux kernel, the following vulnerability has been resolved:
keys: Fix overwrite of key expiration on instantiation
The expiry time of a key is unconditionally overwritten during
instantiation, defaulting to turn it permanent. This causes a problem
for DNS resolution as the expiration set by user-space is overwritten to
TIME64_MAX, disabling further DNS updates. Fix this by restoring the
condition that key_set_expiry is only called when the pre-parser sets a
specific expiry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu: Fix buffer overflow in print_cpu_stall_info()
The rcuc-starvation output from print_cpu_stall_info() might overflow the
buffer if there is a huge difference in jiffies difference. The situation
might seem improbable, but computers sometimes get very confused about
time, which can result in full-sized integers, and, in this case,
buffer overflow.
Also, the unsigned jiffies difference is printed using %ld, which is
normally for signed integers. This is intentional for debugging purposes,
but it is not obvious from the code.
This commit therefore changes sprintf() to snprintf() and adds a
clarifying comment about intention of %ld format.

The most an attacker can do is create local system conditions (heavy load, CPU starvation) that make an RCU stall warning fire.\nAC:H - Three conditions all lie outside attacker control: rcuc kthreads must exist (requires CONFIG_PREEMPT_RT or the boot parameter rcutree.use_softirq=0, non-default on mainstream kernels), an RCU CPU stall must actually be declared, and the jiffies delta must exceed ~1e8 (27.8 h at HZ=1000) or be a corrupted backwards value that the attacker cannot influence. The commit author himself describes the triggering situation as \"improbable\" and dependent on the machine being \"very confused about time.\"\nPR:L - No authentication gate protects the path itself, but reaching it requires being on the system to generate the CPU/RCU starvation load that provokes a stall warning, which an ordinary unprivileged local user can attempt. Choosing the higher of Low versus High since no capability check or root requirement guards the RCU stall detector.\nUI:N - The stall detector fires autonomously from the scheduler-clock interrupt with no victim action required. No file open, mount, or other user operation is involved.\nS:U - The overflow corrupts the kernel stack frame of print_cpu_stall_info() within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-bounds write corrupts adjacent stack frame contents, including the ticks_title char pointer that is dereferenced by the very next pr_err(\"%s\", ...), which can dump arbitrary adjacent kernel memory to the console/dmesg. Memory corruption of this kind is leverageable for kernel information disclosure.\nI:H - This is an out-of-bounds stack write of up to 12 bytes past a 32-byte buffer, overwriting the stack canary, saved registers, and potentially the return address of print_cpu_stall_info(). Per scoring guidance an out-of-bounds write is High integrity impact regardless of how constrained the written bytes are.\nA:H - The overflow occurs in hard-IRQ context with interrupts disabled while holding the raw rnp-\u003elock spinlock; on stack-protector kernels it trips __stack_chk_fail() and panics the machine, and without it the corrupted frame yields a bad pointer dereference or corrupted return leading to an oops. Either outcome is a full kernel crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
workqueue: Fix selection of wake_cpu in kick_pool()
With cpu_possible_mask=0-63 and cpu_online_mask=0-7 the following
kernel oops was observed:
smp: Bringing up secondary CPUs ...
smp: Brought up 1 node, 8 CPUs
Unable to handle kernel pointer dereference in virtual kernel address space

The crash is caused by calling arch_vcpu_is_preempted() for an offline
CPU. To avoid this, select the cpu with cpumask_any_and_distribute()
to mask __pod_cpumask with cpu_online_mask. In case no cpu is left in
the pool, skip the assignment.
tj: This doesn't fully fix the bug as CPUs can still go down between picking
the target CPU and the wake call. Fixing that likely requires adding
cpu_online() test to either the sched or s390 arch code. However, regardless
of how that is fixed, workqueue shouldn't be picking a CPU which isn't
online as that would result in unpredictable and worse behavior.

Summary
In the Linux kernel, the following vulnerability has been resolved:
swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y
Using restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction
with dynamic SWIOTLB (CONFIG_SWIOTLB_DYNAMIC=y) leads to the following
crash when initialising the restricted pools at boot-time:
| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008
| Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP
| pc : rmem_swiotlb_device_init+0xfc/0x1ec
| lr : rmem_swiotlb_device_init+0xf0/0x1ec
| Call trace:
| rmem_swiotlb_device_init+0xfc/0x1ec
| of_reserved_mem_device_init_by_idx+0x18c/0x238
| of_dma_configure_id+0x31c/0x33c
| platform_dma_configure+0x34/0x80
faddr2line reveals that the crash is in the list validation code:
include/linux/list.h:83
include/linux/rculist.h:79
include/linux/rculist.h:106
kernel/dma/swiotlb.c:306
kernel/dma/swiotlb.c:1695
because add_mem_pool() is trying to list_add_rcu() to a NULL
'mem->pools'.
Fix the crash by initialising the 'mem->pools' list_head in
rmem_swiotlb_device_init() before calling add_mem_pool().

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: qcom: uefisecapp: Fix memory related IO errors and crashes
It turns out that while the QSEECOM APP_SEND command has specific fields
for request and response buffers, uefisecapp expects them both to be in
a single memory region. Failure to adhere to this has (so far) resulted
in either no response being written to the response buffer (causing an
EIO to be emitted down the line), the SCM call to fail with EINVAL
(i.e., directly from TZ/firmware), or the device to be hard-reset.
While this issue can be triggered deterministically, in the current form
it seems to happen rather sporadically (which is why it has gone
unnoticed during earlier testing). This is likely due to the two
kzalloc() calls (for request and response) being directly after each
other. Which means that those likely return consecutive regions most of
the time, especially when not much else is going on in the system.
Fix this by allocating a single memory region for both request and
response buffers, properly aligning both structs inside it. This
unfortunately also means that the qcom_scm_qseecom_app_send() interface
needs to be restructured, as it should no longer map the DMA regions
separately. Therefore, move the responsibility of DMA allocation (or
mapping) to the caller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix oops during rmmod on single-CPU platforms
During the removal of the idxd driver, registered offline callback is
invoked as part of the clean up process. However, on systems with only
one CPU online, no valid target is available to migrate the
perf context, resulting in a kernel oops:
BUG: unable to handle page fault for address: 000000000002a2b8
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix uninit-value access in __ip_make_skb()
KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb()
tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a
race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL
while __ip_make_skb() is running, the function will access icmphdr in the
skb even if it is not included. This causes the issue reported by KMSAN.
Check FLOWI_FLAG_KNOWN_NH on fl4->flowi4_flags instead of testing HDRINCL
on the socket.
Also, fl4->fl4_icmp_type and fl4->fl4_icmp_code are not initialized. These
are union in struct flowi4 and are implicitly initialized by
flowi4_init_output(), but we should not rely on specific union layout.
Initialize these explicitly in raw_sendmsg().

Summary
In the Linux kernel, the following vulnerability has been resolved:
firewire: ohci: mask bus reset interrupts between ISR and bottom half
In the FireWire OHCI interrupt handler, if a bus reset interrupt has
occurred, mask bus reset interrupts until bus_reset_work has serviced and
cleared the interrupt.
Normally, we always leave bus reset interrupts masked. We infer the bus
reset from the self-ID interrupt that happens shortly thereafter. A
scenario where we unmask bus reset interrupts was introduced in 2008 in
a007bb857e0b26f5d8b73c2ff90782d9c0972620: If
OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we
will unmask bus reset interrupts so we can log them.
irq_handler logs the bus reset interrupt. However, we can't clear the bus
reset event flag in irq_handler, because we won't service the event until
later. irq_handler exits with the event flag still set. If the
corresponding interrupt is still unmasked, the first bus reset will
usually freeze the system due to irq_handler being called again each
time it exits. This freeze can be reproduced by loading firewire_ohci
with "modprobe firewire_ohci debug=-1" (to enable all debugging output).
Apparently there are also some cases where bus_reset_work will get called
soon enough to clear the event, and operation will continue normally.
This freeze was first reported a few months after a007bb85 was committed,
but until now it was never fixed. The debug level could safely be set
to -1 through sysfs after the module was loaded, but this would be
ineffectual in logging bus reset interrupts since they were only
unmasked during initialization.
irq_handler will now leave the event flag set but mask bus reset
interrupts, so irq_handler won't be called again and there will be no
freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will
unmask the interrupt after servicing the event, so future interrupts
will be caught as desired.
As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be
enabled through sysfs in addition to during initial module loading.
However, when enabled through sysfs, logging of bus reset interrupts will
be effective only starting with the second bus reset, after
bus_reset_work has executed.

We infer the bus\nreset from the self-ID interrupt that happens shortly thereafter. A\nscenario where we unmask bus reset interrupts was introduced in 2008 in\na007bb857e0b26f5d8b73c2ff90782d9c0972620: If\nOHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we\nwill unmask bus reset interrupts so we can log them.\n\nirq_handler logs the bus reset interrupt. However, we can\u0027t clear the bus\nreset event flag in irq_handler, because we won\u0027t service the event until\nlater. irq_handler exits with the event flag still set. If the\ncorresponding interrupt is still unmasked, the first bus reset will\nusually freeze the system due to irq_handler being called again each\ntime it exits. This freeze can be reproduced by loading firewire_ohci\nwith \"modprobe firewire_ohci debug=-1\" (to enable all debugging output).\nApparently there are also some cases where bus_reset_work will get called\nsoon enough to clear the event, and operation will continue normally.\n\nThis freeze was first reported a few months after a007bb85 was committed,\nbut until now it was never fixed. The debug level could safely be set\nto -1 through sysfs after the module was loaded, but this would be\nineffectual in logging bus reset interrupts since they were only\nunmasked during initialization.\n\nirq_handler will now leave the event flag set but mask bus reset\ninterrupts, so irq_handler won\u0027t be called again and there will be no\nfreeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will\nunmask the interrupt after servicing the event, so future interrupts\nwill be caught as desired.\n\nAs a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be\nenabled through sysfs in addition to during initial module loading.\nHowever, when enabled through sysfs, logging of bus reset interrupts will\nbe effective only starting with the second bus reset, after\nbus_reset_work has executed."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KEYS: trusted: Do not use WARN when encode fails
When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference
In cdns_mhdp_atomic_enable(), the return value of drm_mode_duplicate() is
assigned to mhdp_state->current_mode, and there is a dereference of it in
drm_mode_set_name(), which will lead to a NULL pointer dereference on
failure of drm_mode_duplicate().
Fix this bug add a check of mhdp_state->current_mode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix pcluster use-after-free on UP platforms
During stress testing with CONFIG_SMP disabled, KASAN reports as below:
==================================================================
BUG: KASAN: use-after-free in __mutex_lock+0xe5/0xc30
Read of size 8 at addr ffff8881094223f8 by task stress/7789
CPU: 0 PID: 7789 Comm: stress Not tainted 6.0.0-rc1-00002-g0d53d2e882f9 #3

vfs_write+0x555/0x6c0
ksys_write+0xbe/0x160
do_syscall_64+0x3b/0x90
The root cause is that erofs_workgroup_unfreeze() doesn't reset to
orig_val thus it causes a race that the pcluster reuses unexpectedly
before freeing.
Since UP platforms are quite rare now, such path becomes unnecessary.
Let's drop such specific-designed path directly instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/9p: fix uninit-value in p9_client_rpc()
Syzbot with the help of KMSAN reported the following error:

If p9_check_errors() fails early in p9_client_rpc(), req->rc.tag
will not be properly initialized. However, trace_9p_client_res()
ends up trying to print it out anyway before p9_client_rpc()
finishes.
Fix this issue by assigning default values to p9_fcall fields
such as 'tag' and (just in case KMSAN unearths something new) 'id'
during the tag allocation stage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kdb: Fix buffer overflow during tab-complete
Currently, when the user attempts symbol completion with the Tab key, kdb
will use strncpy() to insert the completed symbol into the command buffer.
Unfortunately it passes the size of the source buffer rather than the
destination to strncpy() with predictably horrible results. Most obviously
if the command buffer is already full but cp, the cursor position, is in
the middle of the buffer, then we will write past the end of the supplied
buffer.
Fix this by replacing the dubious strncpy() calls with memmove()/memcpy()
calls plus explicit boundary checks to make sure we have enough space
before we start moving characters around.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix potential index out of bounds in color transformation function
Fixes index out of bounds issue in the color transformation function.
The issue could occur when the index 'i' exceeds the number of transfer
function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, an error message is
logged and the function returns false to indicate an error.
Reported by smatch:

Summary
In the Linux kernel, the following vulnerability has been resolved:
hv_netvsc: Don't free decrypted memory
In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.
The netvsc driver could free decrypted/shared pages if
set_memory_decrypted() fails. Check the decrypted field in the gpadl
to decide whether to free the memory.

No network, adjacent-network, or physical access to the guest is involved.\nAC:L - The host deterministically controls the outcome \u2014 it simply returns an error from the TDVMCALL\u003cMapGPA\u003e or HVCALL_MODIFY_SPARSE_GPA_PAGE_HOST_VISIBILITY hypercall at a moment of its choosing, and the PTE encryption bit has already been cleared by `__change_page_attr_set_clr()` before that call. It can also force unlimited retries via suspend/resume and VF hot-plug cycles, so nothing depends on conditions outside its control.\nPR:N - In the confidential-computing threat model the host holds zero privileges inside the guest \u2014 that is the entire premise of TDX/SEV-SNP \u2014 and needs no guest account or capability to fail the conversion hypercall. The vulnerable path runs at netvsc probe during guest boot with no guest-side authentication.\nUI:N - The GPADL for the receive/send buffers is established automatically during `netvsc_init_buf()` at driver probe on every guest boot, and the host can independently drive further detach/attach cycles via `netvsc_suspend`/`netvsc_resume`. No guest user action is required.\nS:U - The impacted resources are guest kernel and guest userspace memory, which fall under the same security authority as the vulnerable component (the guest Linux kernel). This is a host-to-guest attack, not an escape from the vulnerable component\u0027s scope such as a guest-to-host breakout.\nC:H - Up to 46MB of still-shared pages are returned to the buddy allocator and recycled for arbitrary kernel and user data, which the untrusted host can then read in plaintext \u2014 keys, credentials, and any guest secret that lands in those pages. This is a total loss of confidential-VM confidentiality, repeatable across reinit cycles.\nI:H - The same pages remain host-*writable*, so the host can modify arbitrary reallocated slab objects, page-cache contents, and function pointers in the guest, yielding an arbitrary-write primitive and code execution inside the guest kernel.\nA:H - Guest reuse of pages whose private/shared state disagrees with the guest\u0027s expectation triggers #VE/#VC exceptions and memory corruption in arbitrary recycled kernel structures, leading to guest kernel panic. The host can induce this at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dpll: fix dpll_pin_on_pin_register() for multiple parent pins
In scenario where pin is registered with multiple parent pins via
dpll_pin_on_pin_register(..), all belonging to the same dpll device.
A second call to dpll_pin_on_pin_unregister(..) would cause a call trace,
as it tries to use already released registration resources (due to fix
introduced in b446631f355e). In this scenario pin was registered twice,
so resources are not yet expected to be release until each registered
pin/pin pair is unregistered.
Currently, the following crash/call trace is produced when ice driver is
removed on the system with installed E810T NIC which includes dpll device:
WARNING: CPU: 51 PID: 9155 at drivers/dpll/dpll_core.c:809 dpll_pin_ops+0x20/0x30
RIP: 0010:dpll_pin_ops+0x20/0x30
Call Trace:

Fix by adding a parent pointer as a cookie when creating a registration,
also when searching for it. For the regular pins pass NULL, this allows to
create separated registration for each parent the pin is registered with.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/proc/task_mmu: fix loss of young/dirty bits during pagemap scan
make_uffd_wp_pte() was previously doing:
pte = ptep_get(ptep);
ptep_modify_prot_start(ptep);
pte = pte_mkuffd_wp(pte);
ptep_modify_prot_commit(ptep, pte);
But if another thread accessed or dirtied the pte between the first 2
calls, this could lead to loss of that information. Since
ptep_modify_prot_start() gets and clears atomically, the following is the
correct pattern and prevents any possible race. Any access after the
first call would see an invalid pte and cause a fault:
pte = ptep_modify_prot_start(ptep);
pte = pte_mkuffd_wp(pte);
ptep_modify_prot_commit(ptep, pte);

There is no network-facing consumer of this path.\nAC:L - The attacker owns both sides of the race \u2014 sibling threads continuously writing to the mapped range set the hardware A/D bits while another thread loops PAGEMAP_SCAN with PM_SCAN_WP_MATCHING over millions of PTEs per iteration, so a hit is effectively guaranteed and can be retried without limit. No condition depends on external state the attacker cannot influence.\nPR:L - Only an ordinary unprivileged local account is needed: pagemap_open() requires just PTRACE_MODE_READ (trivial for /proc/self), the PAGEMAP_SCAN ioctl has no capability check, and userfaultfd_syscall_allowed() unconditionally permits UFFD_USER_MODE_ONLY so even vm.unprivileged_userfaultfd=0 does not block UFFD_FEATURE_WP_ASYNC registration. All required Kconfig options (PROC_PAGE_MONITOR, PTE_MARKER_UFFD_WP) are default-y in distro kernels.\nUI:N - The attacker drives the ioctl and the racing writes entirely from its own threads with no victim action required; when targeting another mm the victim\u0027s pre-existing uffd-wp-async registration is passive state, not an interaction.\nS:U - The lost PTE bits corrupt memory managed by the same kernel that contains the flaw, with no crossing of a hypervisor, IOMMU, or sandbox boundary. This is the standard unchanged-scope case for a kernel memory-management defect.\nC:L - Discarding the dirty bit causes a page\u0027s rewritten contents to be dropped and the stale swap-slot contents to be resurrected, so data a process deliberately overwrote or scrubbed (keys, credentials) persists in memory and on the swap device instead of being erased. This is a bounded exposure of previously-written data rather than an arbitrary kernel read primitive.\nI:H - Loss of the dirty bit makes the kernel silently drop modified pages \u2014 swap-cached anonymous pages revert to stale contents and MADV_FREE pages are discarded to zeros via the try_to_unmap_one discard path \u2014 with no error to the application. The attacker can repeat this across an unbounded number of pages, including in another process\u0027s mm it can ptrace-read (e.g. a CRIU- or VMM-managed workload using uffd-wp-async dirty tracking), amounting to total loss of integrity of that memory.\nA:H - Pages silently reverting to stale swap contents or being zeroed out corrupts live program state and reliably renders the affected process \u2014 including a targeted uffd-wp-async user such as a checkpoint/restore agent or live-migration VMM and its guest \u2014 non-functional or crashed. The condition is repeatable at will by an unprivileged local user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppdev: Add an error check in register_device
In register_device, the return value of ida_simple_get is unchecked,
in witch ida_simple_get will use an invalid index value.
To address this issue, index should be checked after ida_simple_get. When
the index value is abnormal, a warning message should be printed, the port
should be dropped, and the value should be recorded.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: carl9170: add a proper sanity check for endpoints
Syzkaller reports [1] hitting a warning which is caused by presence
of a wrong endpoint type at the URB sumbitting stage. While there
was a check for a specific 4th endpoint, since it can switch types
between bulk and interrupt, other endpoints are trusted implicitly.
Similar warning is triggered in a couple of other syzbot issues [2].
Fix the issue by doing a comprehensive check of all endpoints
taking into account difference between high- and full-speed
configuration.
[1] Syzkaller report:
...

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix use-after-free of timer for log writer thread
Patch series "nilfs2: fix log writer related issues".
This bug fix series covers three nilfs2 log writer-related issues,
including a timer use-after-free issue and potential deadlock issue on
unmount, and a potential freeze issue in event synchronization found
during their analysis. Details are described in each commit log.
This patch (of 3):
A use-after-free issue has been reported regarding the timer sc_timer on
the nilfs_sc_info structure.
The problem is that even though it is used to wake up a sleeping log
writer thread, sc_timer is not shut down until the nilfs_sc_info structure
is about to be freed, and is used regardless of the thread's lifetime.
Fix this issue by limiting the use of sc_timer only while the log writer
thread is alive.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nsh: Restore skb->{protocol,data,mac_header} for outer header in nsh_gso_segment().
syzbot triggered various splats (see [0] and links) by a crafted GSO
packet of VIRTIO_NET_HDR_GSO_UDP layering the following protocols:
ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDP
NSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the inner
protocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls
skb_mac_gso_segment() to invoke inner protocol GSO handlers.
nsh_gso_segment() does the following for the original skb before
calling skb_mac_gso_segment()
1. reset skb->network_header
2. save the original skb->{mac_heaeder,mac_len} in a local variable
3. pull the NSH header
4. resets skb->mac_header
5. set up skb->mac_len and skb->protocol for the inner protocol.
and does the following for the segmented skb
6. set ntohs(ETH_P_NSH) to skb->protocol
7. push the NSH header
8. restore skb->mac_header
9. set skb->mac_header + mac_len to skb->network_header
10. restore skb->mac_len
There are two problems in 6-7 and 8-9.
(a)
After 6 & 7, skb->data points to the NSH header, so the outer header
(ETH_P_8021AD in this case) is stripped when skb is sent out of netdev.
Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH),
skb_pull() in the first nsh_gso_segment() will make skb->data point
to the middle of the outer NSH or Ethernet header because the Ethernet
header is not pulled by the second nsh_gso_segment().
(b)
While restoring skb->{mac_header,network_header} in 8 & 9,
nsh_gso_segment() does not assume that the data in the linear
buffer is shifted.
However, udp6_ufo_fragment() could shift the data and change
skb->mac_header accordingly as demonstrated by syzbot.
If this happens, even the restored skb->mac_header points to
the middle of the outer header.
It seems nsh_gso_segment() has never worked with outer headers so far.
At the end of nsh_gso_segment(), the outer header must be restored for
the segmented skb, instead of the NSH header.
To do that, let's calculate the outer header position relatively from
the inner header and set skb->{data,mac_header,protocol} properly.

"value": "AV:L - The vulnerable path is entered from `packet_sendmsg()` on a local AF_PACKET socket using PACKET_VNET_HDR to hand the stack a crafted ETH_P_8021AD/ETH_P_NSH/IPv6/UDP GSO skb. NSH has no GRO/receive-offload handler, so a remote peer cannot cause the kernel to construct an NSH-typed GSO skb with an outer header; the trigger must be locally injected.\nAC:L - The attacker fully controls the packet layering, the outer header length and the GSO parameters, so the broken header restore is hit deterministically on every send \u2014 syzbot produced C reproducers for both reported splats. No race, timing window or uncontrollable memory layout is involved.\nPR:L - Sending the crafted GSO frame requires only a raw packet socket (CAP_NET_RAW), which an unprivileged user obtains inside a user+network namespace via `unshare -Urn`, and the nsh offload handler can be autoloaded unprivileged through the openvswitch generic-netlink family alias (`ctrl_getfamily()` calls `request_module()` with no capability check). No real root or init-namespace privilege is needed.\nUI:N - The attacker triggers the entire sequence himself with a single sendto() on his own socket. No victim action, mount, or file open is required.\nS:U - The corruption is confined to kernel skb metadata and buffers handled by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Each segment\u0027s `mac_header`/`network_header` are set to offsets belonging to a different skb, so the kernel reads uninitialized/stale heap headroom and interprets it as the outer Ethernet header (KMSAN uninit-value in `ipvlan_process_outbound` reading `ethh-\u003eh_dest`); those recycled heap bytes steer routing and can be emitted on the wire, and the negative `skb_network_offset()` extends reads outside the packet data rather than confining them to a small bounded field.\nI:H - The skb geometry corruption makes the kernel write protocol header fields (IPv6 `payload_len`, `nexthdr`) at mis-located offsets and transmit frames whose outer 802.1AD/Ethernet header has been stripped or truncated, letting an attacker punch packets out with framing the stack never intended and defeating VLAN-based segmentation; corrupted header offsets fed to NIC offload descriptors extend this to attacker-influenced buffer regions.\nA:H - syzbot reproduced kernel splats on this path (KMSAN uninit-value via `ipvlan_queue_xmit` and a `WARNING in gre_tap_xmit` from `pskb_inet_may_pull()` on a wrapped length), which panic the machine under panic_on_warn, and the unchecked `__skb_push()` plus negative `skb_network_offset()` arithmetic can drive downstream `skb_pull()`/`skb_push()` into `BUG_ON(skb-\u003elen \u003c skb-\u003edata_len)` / `skb_under_panic()`. The attacker can repeat the send in a loop."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: add error handle to avoid out-of-bounds
if the sdma_v4_0_irq_id_to_seq return -EINVAL, the process should
be stop to avoid out-of-bounds read, so directly return -EINVAL.

A local user with render-node access can keep the SDMA engines and their trap/error interrupts firing continuously to reach the handler repeatedly.\nPR:L - Exercising SDMA queues and provoking trap interrupts only requires opening the unprivileged DRM render node, which is group-readable to ordinary logged-in users on desktops, Android devices, and GPU cloud/container instances. No CAP_SYS_ADMIN or root in the initial namespace is needed.\nUI:N - The interrupt handler runs asynchronously from GPU activity the attacker\u0027s own process generates; no victim must open a file, mount anything, or take any action.\nS:U - The corruption is confined to kernel memory within the same security authority as the host kernel; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `adev-\u003esdma.instance[0xFFFFFFEA]` is an unbounded out-of-bounds read many gigabytes beyond the array, and `amdgpu_fence_process()` then dereferences the resulting `struct amdgpu_ring`, reading `fence_drv.last_seq`, `sync_seq`, `num_fences_mask`, `adev`, and the `fences[]` pointer array from that location \u2014 arbitrary kernel memory read, not a bounded few-byte overread.\nI:H - The wild pointer is not merely read: `amdgpu_fence_process()` performs `atomic_cmpxchg()` on `drv-\u003elast_seq`, `timer_delete()` on `fence_drv.fallback_timer`, `RCU_INIT_POINTER(*ptr, NULL)` stores into `drv-\u003efences[]`, and `dma_fence_put()` (a refcount decrement plus potential release callback) on the garbage pointer \u2014 out-of-bounds writes and a refcount-decrement primitive that are the classic building blocks for control-flow hijacking.\nA:H - Dereferencing a pointer several terabytes out of range in hard-interrupt context faults on unmapped kernel memory, producing an oops/panic that cannot be recovered from in IRQ context, and the corrupting writes and bogus `dma_fence_put()` release paths add further crash modes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Skip on writeback when it's not applicable
[WHY]
dynamic memory safety error detector (KASAN) catches and generates error
messages "BUG: KASAN: slab-out-of-bounds" as writeback connector does not
support certain features which are not initialized.
[HOW]
Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: gtp: Fix Use-After-Free in gtp_dellink
Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal
of gtp_dellink, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.

Received GTP-U packets only look up PDP contexts and never reach the deletion path, so no remote packet can drive the vulnerable traversal.\nAC:L - The attacker controls both sides of the race: they choose the hash size and the number of PDP contexts (lengthening the unprotected traversal), can pin CPUs and generate load to force preemption inside the window, and can drive RCU grace periods from other tasks. On preemptible-RCU kernels the grace period reliably completes mid-loop, and heap grooming to reallocate the freed `pdp_ctx` is standard slab-spray work under attacker control.\nPR:L - The trigger is gated by `netlink_net_capable(CAP_NET_ADMIN)`, which is satisfied with CAP_NET_ADMIN inside a user-namespace-owned netns (`unshare -Urn`), and the netns-teardown path runs gtp_dellink automatically when such a namespace is destroyed. In containerized mobile-core deployments the PDP contexts are populated by a privileged daemon from remote signaling, so a userns-root attacker needs no real root to reach the vulnerable loop.\nUI:N - The attacker performs the link deletion or namespace exit themselves; no action by any other user or administrator is required.\nS:U - The use-after-free corrupts kernel heap memory within the same security authority; there is no crossing of a VM, IOMMU, or hypervisor boundary.\nC:H - The traversal reads a freed `pdp_ctx` whose contents the attacker can control via heap spraying, and the resulting attacker-influenced pointer is dereferenced as a `pdp_ctx`, enabling controlled reads of kernel memory and full kernel-memory disclosure once combined with the write primitive.\nI:H - The stale pointer is passed to `pdp_context_delete()`, so `hlist_del_rcu()` performs an unlink write (`*pprev = next; next-\u003epprev = pprev`) at attacker-influenced addresses, and the queued `pdp_context_free()` later does `sock_put()` on an arbitrary pointer plus an arbitrary `kfree()` \u2014 a path to arbitrary write and privilege escalation.\nA:H - Even without successful heap grooming the loop dereferences poisoned/freed slab memory and then unlinks and frees it again, producing a guaranteed oops, double free, or slab corruption panic that takes the machine down."

The window is wide (no shared lock between the free and the use) and the attempt is infinitely retryable.\nPR:L - An unprivileged local user reaching the Bluetooth HCI device-management interfaces can drive both the adapter power-down path and the transport teardown that frees `msft_data`; no real root in the initial namespace is required to win this race. This matches the privilege level assigned to the equivalent HCI teardown use-after-frees (CVE-2024-53208, CVE-2024-58013, CVE-2024-58241).\nUI:N - The race is driven entirely by the attacker\u0027s own sequence of device-lifecycle and power-state operations. No victim action or interaction is needed at any point.\nS:U - The freed object, the corrupted heap, and the resulting compromise all reside within the kernel\u0027s own security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - After the freed `msft_data` slab is reallocated with sprayed data, `msft_do_close()` walks `msft-\u003ehandle_map` and reads `handle_data-\u003emgmt_handle` from attacker-controlled memory and feeds it to `idr_find()`, yielding an arbitrary kernel read primitive. Any use-after-free of this shape enables disclosure of arbitrary kernel memory.\nI:H - The same list walks perform `list_del()` on attacker-controlled `list_head` pointers \u2014 an arbitrary write of pointer values to attacker-chosen kernel addresses \u2014 followed by `kfree()` of an attacker-chosen pointer, and `mutex_lock()` on a corrupted `filter_lock`. These are classic primitives for control-flow hijacking and local privilege escalation.\nA:H - Even without successful exploitation, the slab-use-after-free reliably corrupts kernel state and causes an oops or panic, as demonstrated by the KASAN report in `__mutex_lock` from `kworker/u5:2`. This is a complete denial of service that the attacker can trigger at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix hashtab overflow check on 32-bit arches
The hashtab code relies on roundup_pow_of_two() to compute the number of
hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code. So apply the same
fix to hashtab, by moving the overflow check to before the roundup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure
The kcalloc() in dmirror_device_evict_chunk() will return null if the
physical memory has run out. As a result, if src_pfns or dst_pfns is
dereferenced, the null pointer dereference bug will happen.
Moreover, the device is going away. If the kcalloc() fails, the pages
mapping a chunk could not be evicted. So add a __GFP_NOFAIL flag in
kcalloc().
Finally, as there is no need to have physically contiguous memory, Switch
kcalloc() to kvcalloc() in order to avoid failing allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: fix null pointer dereference within spi_sync
If spi_sync() is called with the non-empty queue and the same spi_message
is then reused, the complete callback for the message remains set while
the context is cleared, leading to a null pointer dereference when the
callback is invoked from spi_finalize_current_message().
With function inlining disabled, the call stack might look like this:
_raw_spin_lock_irqsave from complete_with_flags+0x18/0x58
complete_with_flags from spi_complete+0x8/0xc
spi_complete from spi_finalize_current_message+0xec/0x184
spi_finalize_current_message from spi_transfer_one_message+0x2a8/0x474
spi_transfer_one_message from __spi_pump_transfer_message+0x104/0x230
__spi_pump_transfer_message from __spi_transfer_message_noqueue+0x30/0xc4
__spi_transfer_message_noqueue from __spi_sync+0x204/0x248
__spi_sync from spi_sync+0x24/0x3c
spi_sync from mcp251xfd_regmap_crc_read+0x124/0x28c [mcp251xfd]
mcp251xfd_regmap_crc_read [mcp251xfd] from _regmap_raw_read+0xf8/0x154
_regmap_raw_read from _regmap_bus_read+0x44/0x70
_regmap_bus_read from _regmap_read+0x60/0xd8
_regmap_read from regmap_read+0x3c/0x5c
regmap_read from mcp251xfd_alloc_can_err_skb+0x1c/0x54 [mcp251xfd]
mcp251xfd_alloc_can_err_skb [mcp251xfd] from mcp251xfd_irq+0x194/0xe70 [mcp251xfd]
mcp251xfd_irq [mcp251xfd] from irq_thread_fn+0x1c/0x78
irq_thread_fn from irq_thread+0x118/0x1f4
irq_thread from kthread+0xd8/0xf4
kthread from ret_from_fork+0x14/0x28
Fix this by also setting message->complete to NULL when the transfer is
complete.

Summary
In the Linux kernel, the following vulnerability has been resolved:
amd/amdkfd: sync all devices to wait all processes being evicted
If there are more than one device doing reset in parallel, the first
device will call kfd_suspend_all_processes() to evict all processes
on all devices, this call takes time to finish. other device will
start reset and recover without waiting. if the process has not been
evicted before doing recover, it will be restored, then caused page
fault.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix Use-After-Free in tcp_ao_connect_init
Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal
of tcp_ao_connect_init, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Discard command completions in internal error
Fix use after free when FW completion arrives while device is in
internal error state. Avoid calling completion handler in this case,
since the device will flush the command interface and trigger all
completions manually.

No capability is needed for those operations.\nUI:N - The double `cmd_ent_put()` fires from the async EQ interrupt handler with no victim action involved; the attacker only needs to have commands outstanding when the device faults.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - After the entry is freed, `ent-\u003eout`, `ent-\u003elay` and `ent-\u003euout` are read from reallocated memory and `mlx5_copy_from_msg()` copies firmware response data through those attacker-groomable pointers, giving an arbitrary kernel read/disclosure primitive.\nI:H - The stale completion path performs `callback(err, context)` \u2014 an indirect call through a function pointer read out of freed memory \u2014 plus writes via `ent-\u003eout`/`ent-\u003euout` and `mlx5_free_cmd_msg()`/`free_msg()` on freed pointers, yielding arbitrary write and control-flow hijack primitives.\nA:H - The reported symptom is a `refcount_t: underflow; use-after-free` WARN in hard-IRQ context (fatal under panic_on_warn); the extra put also frees a live command entry and corrupts the command-slot bitmask and semaphore, leading to oops/panic and a wedged command interface."

Summary
In the Linux kernel, the following vulnerability has been resolved:
enic: Validate length of nl attributes in enic_set_vf_port
enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE
is of length PORT_PROFILE_MAX and that the nl attributes
IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.
These attributes are validated (in the function do_setlink in rtnetlink.c)
using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE
as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and
IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation
using the policy is for the max size of the attributes and not on exact
size so the length of these attributes might be less than the sizes that
enic_set_vf_port expects. This might cause an out of bands
read access in the memcpys of the data of these
attributes in enic_set_vf_port.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/9p: only translate RWX permissions for plain 9P2000
Garbage in plain 9P2000's perm bits is allowed through, which causes it
to be able to set (among others) the suid bit. This was presumably not
the intent since the unix extended bits are handled explicitly and
conditionally on .u.

"value": "AV:N - The malicious `perm` word is parsed straight out of an Rstat response from the 9P peer, and v9fs supports `trans=tcp` (port 564) as well as rdma/xen, so the attacker is a remote or spoofed file server across a network. No local access to the client is needed to deliver the crafted metadata.\nAC:L - The server simply sets bit 0x800 in the stat `perm` field \u2014 fully deterministic, no race or memory-layout dependency. It also controls the only other precondition, since `p9_client_version()` lets the server downgrade the session to plain 9P2000 by answering \"9P2000\" to a \"9P2000.L\" TVERSION.\nPR:N - v9fs calls `p9_client_attach()` with `afid = NULL`, so no 9P authentication is performed, and the transport is plaintext \u2014 the attacker holds no credentials or privileges on the client system. The client blindly trusts the mode bits of whatever peer answers.\nUI:R - The forged setuid bit is applied to the inode with no user action, but the privilege gain is realized only when a local process executes the planted binary from the mount. That execution is performed by a party other than the remote attacker.\nS:U - The impact is confined to the client system\u0027s own user/privilege model \u2014 standard privilege escalation within one security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - Execution of the forged setuid binary yields the mount\u0027s `dfltuid`, which is commonly configured as 0 for legacy 9P2000 mounts, giving read access to all files on the system. Forged setgid/sticky bits likewise subvert the client\u0027s access-control decisions in `generic_permission()`.\nI:H - Beyond directly corrupting inode permission metadata, the resulting setuid-`dfltuid` (typically root) execution allows arbitrary modification of system files and state. v9fs never sets `SB_NOSUID` and cannot be mounted from a user namespace, so `bprm_fill_uid()` honors the bit.\nA:H - With execution as `dfltuid=0` obtained through the forged setuid bit, the attacker attains full control of the client and can halt or crash the system at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - validate slices count returned by FW
The function adf_send_admin_tl_start() enables the telemetry (TL)
feature on a QAT device by sending the ICP_QAT_FW_TL_START message to
the firmware. This triggers the FW to start writing TL data to a DMA
buffer in memory and returns an array containing the number of
accelerators of each type (slices) supported by this HW.
The pointer to this array is stored in the adf_tl_hw_data data
structure called slice_cnt.
The array slice_cnt is then used in the function tl_print_dev_data()
to report in debugfs only statistics about the supported accelerators.
An incorrect value of the elements in slice_cnt might lead to an out
of bounds memory read.
At the moment, there isn't an implementation of FW that returns a wrong
value, but for robustness validate the slice count array returned by FW.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpu: Re-enable CPU mitigations by default for !X86 architectures
Rename x86's to CPU_MITIGATIONS, define it in generic code, and force it
on for all architectures exception x86. A recent commit to turn
mitigations off by default if SPECULATION_MITIGATIONS=n kinda sorta
missed that "cpu_mitigations" is completely generic, whereas
SPECULATION_MITIGATIONS is x86-specific.
Rename x86's SPECULATIVE_MITIGATIONS instead of keeping both and have it
select CPU_MITIGATIONS, as having two configs for the same thing is
unnecessary and confusing. This will also allow x86 to use the knob to
manage mitigations that aren't strictly related to speculative
execution.
Use another Kconfig to communicate to common code that CPU_MITIGATIONS
is already defined instead of having x86's menu depend on the common
CPU_MITIGATIONS. This allows keeping a single point of contact for all
of x86's mitigations, and it's not clear that other architectures *want*
to allow disabling mitigations at compile-time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate request buffer size in smb2_allocate_rsp_buf()
The response buffer should be allocated in smb2_allocate_rsp_buf
before validating request. But the fields in payload as well as smb2 header
is used in smb2_allocate_rsp_buf(). This patch add simple buffer size
validation to avoid potencial out-of-bounds in request buffer.

Although the queued entries originate from network packets, the vulnerable code path is entered only through a local netlink syscall.\nAC:L - The attacker deterministically controls both preconditions: they populate `queue_list` by binding an NFQUEUE and never issuing verdicts on their own self-generated traffic, then trigger the flush by closing the socket or sending UNBIND. No race must be won and no uncontrollable state is required \u2014 the RCU callback always executes `nfqnl_flush()` on a non-empty queue.\nPR:L - `nfnetlink_rcv()` gates on `netlink_net_capable(skb, CAP_NET_ADMIN)`, which resolves to `ns_capable()` against the netns\u0027s user_ns, so an unprivileged user obtains it via `unshare -Urn`; nftables/iptables NFQUEUE targets and loopback traffic are fully functional inside that namespace. No real root in the initial namespace is needed.\nUI:N - The attacker performs every step themselves \u2014 creating the namespace, binding the queue, generating the packets, and destroying the instance. No victim action or cooperation is involved.\nS:U - The unprotected dereference and its consequences are confined to the kernel\u0027s own security authority; there is no crossing of a VM, hypervisor, or IOMMU boundary. This is a standard in-kernel memory-safety issue.\nC:H - `nf_reinject()` performs `rcu_dereference()` on `net-\u003enf.hooks_*[hooknum]` with no RCU read-side protection, and `nf_hook_entries` objects are reclaimed via `call_rcu(\u0026head-\u003ehead, __nf_hook_entries_free)` \u2014 so the read can land on freed memory that an attacker can groom via heap spraying, disclosing kernel data and pointers through the subsequently read `num_hook_entries` and `hooks[]` array.\nI:H - A use-after-free of `struct nf_hook_entries` exposes an array of hook function pointers that `nf_reinject()` indexes as `\u0026hooks-\u003ehooks[i]` and invokes via `nf_hook_entry_hookfn()`/`nf_iterate()` on the REPEAT/ACCEPT paths, giving a realloc-and-control primitive suitable for control-flow hijack and privilege escalation.\nA:H - The reproducible syzbot outcome is a `WARNING: suspicious RCU usage` lockdep splat from softirq context, which panics outright on the many production and hardened deployments booted with `panic_on_warn=1`; a real hook-table use-after-free additionally causes oops or panic. Either way the result is a full kernel-level denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/debugfs: Prevent use-after-free from occurring after cdev removal
Since thermal_debug_cdev_remove() does not run under cdev->lock, it can
run in parallel with thermal_debug_cdev_state_update() and it may free
the struct thermal_debugfs object used by the latter after it has been
checked against NULL.
If that happens, thermal_debug_cdev_state_update() will access memory
that has been freed already causing the kernel to crash.
Address this by using cdev->lock in thermal_debug_cdev_remove() around
the cdev->debugfs value check (in case the same cdev is removed at the
same time in two different threads) and its reset to NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: max3100: Update uart_driver_registered on driver removal
The removal of the last MAX3100 device triggers the removal of
the driver. However, code doesn't update the respective global
variable and after insmod — rmmod — insmod cycle the kernel
oopses:
max3100 spi-PRP0001:01: max3100_probe: adding port 0
BUG: kernel NULL pointer dereference, address: 0000000000000408
...
RIP: 0010:serial_core_register_port+0xa0/0x840
...
max3100_probe+0x1b6/0x280 [max3100]
spi_probe+0x8d/0xb0
Update the actual state so next time UART driver will be registered
again.
Hugo also noticed, that the error path in the probe also affected
by having the variable set, and not cleared. Instead of clearing it
move the assignment after the successfull uart_register_driver() call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_expr_type_get()
nft_unregister_expr() can concurrent with __nft_expr_type_get(),
and there is not any protection when iterate over nf_tables_expressions
list in __nft_expr_type_get(). Therefore, there is potential data-race
of nf_tables_expressions list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_expressions
list in __nft_expr_type_get(), and use rcu_read_lock() in the caller
nft_expr_type_get() to protect the entire type query process.

"value": "AV:L - The vulnerable path is reached only through NETLINK_NETFILTER messages (NFT_MSG_NEWRULE/NEWSET batches) sent by a local process on the same host. Per kernel scoring guidance, netfilter/nftables netlink configuration is a local attack vector.\nAC:L - The attacker fully controls the reader side (unbounded NFT_MSG_NEWRULE batches in one netns) and can drive the writer side by forcing expression-module autoload from a second netns, where nf_tables_module_autoload() intentionally releases commit_mutex before request_module(); because the writer holds only the global nfnl mutex and the reader only the per-netns commit_mutex, the two run concurrently with no shared lock and the race can be retried indefinitely.\nPR:L - nfnetlink gates on netlink_net_capable(skb, CAP_NET_ADMIN), which resolves to ns_capable() against the network namespace\u0027s owning user namespace, so an ordinary unprivileged user obtains it with \"unshare -Urn\". No real root or init-namespace capability is needed.\nUI:N - The attacker performs the entire sequence \u2014 creating namespaces, issuing nftables batches, and triggering module autoload \u2014 with no action by any other user or administrator.\nS:U - The race and its consequences are confined to the kernel of the same host; there is no crossing into a different security authority such as a hypervisor or IOMMU boundary.\nC:H - Losing the RCU protection lets nft_expr_type_get() retain a pointer into module memory past free_module()\u0027s synchronize_rcu(), so type-\u003eowner, type-\u003ename, type-\u003emaxattr and type-\u003epolicy are read from freed and potentially reclaimed memory; an attacker-controlled reclaim of that module-region allocation combined with the attacker-supplied nla_policy parse yields kernel memory disclosure.\nI:H - try_module_get() performs an atomic increment through a dangling type-\u003eowner pointer, giving a write into freed memory, and type-\u003eselect_ops/type-\u003eops become indirect calls through freed module-region storage that can be reclaimed (e.g. by another module load or BPF JIT allocation), making control-flow hijack achievable.\nA:H - Dereferencing the stale nft_expr_type and the freed struct module after the module\u0027s vmalloc\u0027d memory is released causes an oops or panic, and the unsynchronized traversal of a concurrently modified list can itself derail into invalid pointers."

After git bisecting and digging into the code, I believe the root cause is
that _deferred_list field of folio is unioned with _hugetlb_subpool field.
In __update_and_free_hugetlb_folio(), folio->_deferred_

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: zswap: fix shrinker NULL crash with cgroup_disable=memory
Christian reports a NULL deref in zswap that he bisected down to the zswap
shrinker. The issue also cropped up in the bug trackers of libguestfs [1]
and the Red Hat bugzilla [2].
The problem is that when memcg is disabled with the boot time flag, the
zswap shrinker might get called with sc->memcg == NULL. This is okay in
many places, like the lruvec operations. But it crashes in
memcg_page_state() - which is only used due to the non-node accounting of
cgroup's the zswap memory to begin with.
Nhat spotted that the memcg can be NULL in the memcg-disabled case, and I
was then able to reproduce the crash locally as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: fix uninitialised kfifo
If a line is requested with debounce, and that results in debouncing
in software, and the line is subsequently reconfigured to enable edge
detection then the allocation of the kfifo to contain edge events is
overlooked. This results in events being written to and read from an
uninitialised kfifo. Read events are returned to userspace.
Initialise the kfifo in the case where the software debounce is
already active.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Check bloom filter map value size
This patch adds a missing check to bloom filter creating, rejecting
values above KMALLOC_MAX_SIZE. This brings the bloom map in line with
many other map types.
The lack of this protection can cause kernel crashes for value sizes
that overflow int's. Such a crash was caught by syzkaller. The next
patch adds more guard-rails at a lower level.

There is no race, no timing window, and no memory-layout precondition needed to reach the out-of-bounds loop.\nPR:L - `bpf_map_push_elem` is in the unprivileged section of `bpf_base_func_proto()`, and bloom-filter map creation has no per-map-type capability gate at all on 5.16\u20136.3 (only `sysctl_unprivileged_bpf_disabled`), while on 6.9 a delegated bpffs BPF token grants `ns_capable(userns, CAP_BPF)` to an unprivileged containerized process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix possible use-after-free issue in ftrace_location()
KASAN reports a bug:
BUG: KASAN: use-after-free in ftrace_location+0x90/0x120
Read of size 8 at addr ffff888141d40010 by task insmod/424
CPU: 8 PID: 424 Comm: insmod Tainted: G W 6.9.0-rc2+

The root cause is that, in lookup_rec(), ftrace record of some address
is being searched in ftrace pages of some module, but those ftrace pages
at the same time is being freed in ftrace_release_mod() as the
corresponding module is being deleted:
CPU1 | CPU2
register_kprobes() { | delete_module() {
check_kprobe_address_safe() { |
arch_check_ftrace_location() { |
ftrace_location() { |
lookup_rec() // USE! | ftrace_release_mod() // Free!
To fix this issue:
1. Hold rcu lock as accessing ftrace pages in ftrace_location_range();
2. Use ftrace_location_range() instead of lookup_rec() in
ftrace_location();
3. Call synchronize_rcu() before freeing any ftrace pages both in
ftrace_process_locs()/ftrace_release_mod()/ftrace_free_mem().

There is no remote or adjacent-network path into ftrace page management.\nAC:L - The attacker controls both sides of the race and can loop them concurrently \u2014 repeatedly registering kprobes/fprobes on one CPU while loading/unloading a module on another \u2014 and the window spans the entire unlocked `pg-\u003enext`/bsearch walk, which is why the reporter hit it with a plain `insmod` of the sample kprobe module. `CONFIG_DYNAMIC_FTRACE` is enabled in virtually all production kernels, so no rare configuration is needed.\nPR:L - The reader side is reachable by a low-privileged tracing-capable task (CAP_PERFMON/CAP_BPF, routinely granted to containerised monitoring agents rather than full root), and the free side can be triggered by an unprivileged task via module autoloading (`request_module()` from AF_ALG bind or socket-family aliases) as well as by module load/unload. No full init-namespace root is required for the whole chain.\nUI:N - The attacker triggers both the kprobe/ftrace registration and the module load/unload entirely on their own; no victim action or cooperation is involved.\nS:U - The use-after-free is in kernel heap/page memory and its consequences stay within the kernel\u0027s own security authority \u2014 no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `lookup_rec()` reads freed `struct ftrace_page` objects and freed record pages, and the harvested contents (`rec-\u003eip`) are returned to the caller and observable through kprobe/ftrace state, exposing whatever reallocated kernel data now occupies those pages.\nI:H - The address returned from freed memory is consumed as a code-patching target \u2014 stored as `tr-\u003eip` for BPF trampolines and installed into ftrace filter hashes \u2014 so heap spraying of the reclaimed pages can steer kernel text modification to an attacker-chosen address, giving a write/control-flow-hijack primitive.\nA:H - Traversing the freed `pg-\u003enext` list and bsearching freed record pages dereferences wild pointers, producing an oops or panic; the race can be retried indefinitely to force a crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Avoid memcpy field-spanning write WARNING
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver
prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)
WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8
replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended
to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array
declaration and clarify that it has flexible length. Also, adjust the
memory allocation size to match the change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: avoid crash when parsed profile name is empty
When processing a packed profile in unpack_profile() described like
"profile :ns::samba-dcerpcd /usr/lib*/samba/{,samba/}samba-dcerpcd {...}"
a string ":samba-dcerpcd" is unpacked as a fully-qualified name and then
passed to aa_splitn_fqname().
aa_splitn_fqname() treats ":samba-dcerpcd" as only containing a namespace.
Thus it returns NULL for tmpname, meanwhile tmpns is non-NULL. Later
aa_alloc_profile() crashes as the new profile name is NULL now.
general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN NOPTI

RIP: 0010:strlen+0x1e/0xa0
It seems such behaviour of aa_splitn_fqname() is expected and checked in
other places where it is called (e.g. aa_remove_profiles). Well, there
is an explicit comment "a ns name without a following profile is allowed"
inside.
AFAICS, nothing can prevent unpacked "name" to be in form like
":samba-dcerpcd" - it is passed from userspace.
Deny the whole profile set replacement in such case and inform user with
EPROTO and an explaining message.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: make sure that WRITTEN is set on all metadata blocks
We previously would call btrfs_check_leaf() if we had the check
integrity code enabled, which meant that we could only run the extended
leaf checks if we had WRITTEN set on the header flags.
This leaves a gap in our checking, because we could end up with
corruption on disk where WRITTEN isn't set on the leaf, and then the
extended leaf checks don't get run which we rely on to validate all of
the item pointers to make sure we don't access memory outside of the
extent buffer.
However, since 732fab95abe2 ("btrfs: check-integrity: remove
CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call
btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only
ever call it on blocks that are being written out, and thus have WRITTEN
set, or that are being read in, which should have WRITTEN set.
Add checks to make sure we have WRITTEN set appropriately, and then make
sure __btrfs_check_leaf() always does the item checking. This will
protect us from file systems that have been corrupted and no longer have
WRITTEN set on some of the blocks.
This was hit on a crafted image tweaking the WRITTEN bit and reported by
KASAN as out-of-bound access in the eb accessors. The example is a dir
item at the end of an eb.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group
The perf tool allows users to create event groups through following
cmd [1], but the driver does not check whether the array index is out
of bounds when writing data to the event_group array. If the number of
events in an event_group is greater than HNS3_PMU_MAX_HW_EVENTS, the
memory write overflow of event_group array occurs.
Add array index check to fix the possible array out of bounds violation,
and return directly when write new events are written to array bounds.
There are 9 different events in an event_group.
[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}

Every condition is under the attacker\u0027s direct control.\nPR:L - An unprivileged local account suffices on the realistic deployment for this driver \u2014 HiSilicon Kunpeng ARM64 servers with NIC PMU profiling enabled, where `kernel.perf_event_paranoid` is set to 0/-1 or CAP_PERFMON is delegated to an observability agent; CAP_PERFMON is explicitly a de-privileged, delegatable capability rather than real root/admin. No authentication beyond a local login is needed, and the OOB write itself executes in `event_init()` before `perf_allow_cpu()` is ever consulted.\nUI:N - The attacker triggers the entire sequence from its own process via repeated `perf_event_open()` calls. No action by any other user or administrator is involved.\nS:U - The out-of-bounds write corrupts the kernel stack of the calling task within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The bug is kernel-stack memory corruption whose written value is a slab pointer to an attacker-groomed `struct perf_event`, landing on adjacent frame state (canary/saved-register slot) that can be leveraged to influence subsequent kernel execution and disclose kernel memory. Per the memory-corruption guidance this is scored High.\nI:H - This is an out-of-bounds *write* past a stack array, and the attacker controls which `perf_event` object\u0027s address is written by ordering the group\u0027s event allocations, giving corruption of control-relevant stack data. Out-of-bounds writes are scored High.\nA:H - On kernels built with CONFIG_STACKPROTECTOR_STRONG (standard for arm64 distro/server kernels) the overwritten slot is the stack canary, so `__stack_chk_fail()` invokes `panic()` unconditionally \u2014 a guaranteed, repeatable full system crash; without the protector it corrupts saved frame state and oopses."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:
Cleanup Thread | Worker Thread
sco_sock_release |
sco_sock_close |
__sco_sock_close |
sco_sock_set_timer |
schedule_delayed_work |
sco_sock_kill | (wait a time)
sock_put(sk) //FREE | sco_sock_timeout
| sock_hold(sk) //USE
The KASAN report triggered by POC is shown below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracefs: Reset permissions on remount if permissions are options
There's an inconsistency with the way permissions are handled in tracefs.
Because the permissions are generated when accessed, they default to the
root inode's permission if they were never set by the user. If the user
sets the permissions, then a flag is set and the permissions are saved via
the inode (for tracefs files) or an internal attribute field (for
eventfs).
But if a remount happens that specify the permissions, all the files that
were not changed by the user gets updated, but the ones that were are not.
If the user were to remount the file system with a given permission, then
all files and directories within that file system should be updated.
This can cause security issues if a file's permission was updated but the
admin forgot about it. They could incorrectly think that remounting with
permissions set would update all files, but miss some.
For example:
# cd /sys/kernel/tracing
# chgrp 1002 current_tracer
# ls -l
[..]
-rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root root 0 May 1 21:25 dynamic_events
-r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root root 0 May 1 21:25 enabled_functions
Where current_tracer now has group "lkp".
# mount -o remount,gid=1001 .
# ls -l
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events
-r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root tracing 0 May 1 21:25 enabled_functions
Everything changed but the "current_tracer".
Add a new link list that keeps track of all the tracefs_inodes which has
the permission flags that tell if the file/dir should use the root inode's
permission or not. Then on remount, clear all the flags so that the
default behavior of using the root inode's permission is done for all
files and directories.

They could incorrectly think that remounting with\npermissions set would update all files, but miss some.\n\nFor example:\n\n # cd /sys/kernel/tracing\n # chgrp 1002 current_tracer\n # ls -l\n[..]\n -rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb\n -rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb\n -r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb\n -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer\n -rw-r----- 1 root root 0 May 1 21:25 dynamic_events\n -r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info\n -r--r----- 1 root root 0 May 1 21:25 enabled_functions\n\nWhere current_tracer now has group \"lkp\".\n\n # mount -o remount,gid=1001 .\n # ls -l\n -rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb\n -rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb\n -r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb\n -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer\n -rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events\n -r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info\n -r--r----- 1 root tracing 0 May 1 21:25 enabled_functions\n\nEverything changed but the \"current_tracer\".\n\nAdd a new link list that keeps track of all the tracefs_inodes which has\nthe permission flags that tell if the file/dir should use the root inode\u0027s\npermission or not. Then on remount, clear all the flags so that the\ndefault behavior of using the root inode\u0027s permission is done for all\nfiles and directories."

There is no network-reachable path to tracefs permission handling.\nAC:L - The stale-permission condition is deterministic \u2014 no race, no memory-layout or timing dependency \u2014 and the attacker can set the pinning flag themselves, since fs/attr.c:chown_ok() allows an owner\u0027s no-op self-chown and chgrp_ok() allows an owner chgrp to their own group, so a granted user can pin every tracefs file at will. Remounting with uid=/gid= is the documented, routinely used way to manage tracefs ownership, so the exploited state arises in normal administration.\nPR:L - The attacker needs only an unprivileged local account that holds (or previously held) tracefs access via the uid=/gid= mount option or the tracing group; no CAP_SYS_ADMIN, CAP_CHOWN or root is required, because setting the pinning flag is permitted to the file\u0027s own owner. Root privileges are never needed on the attacker\u0027s side.\nUI:N - Once the file system is in the vulnerable state, the attacker simply exercises retained read/write access to tracefs with no action required from any other user. The administrator\u0027s remount is a routine configuration operation that establishes the state, not an attacker-induced victim interaction at exploitation time.\nS:U - The unauthorized access and its consequences stay within the kernel/OS security authority managing tracefs; no VM, IOMMU, or container-host boundary is crossed.\nC:H - Retained access to tracefs yields the ring buffer (`trace`, `trace_pipe`, `trace_pipe_raw`) containing kernel addresses and other processes\u0027 syscall data, and writable `kprobe_events`/`dynamic_events` gives probe fetch arguments that dereference and dump arbitrary kernel memory \u2014 an effective arbitrary kernel-read primitive that also defeats KASLR.\nI:H - Group/owner write access is retained on 0640 control files, letting the attacker install kprobes/uprobes, switch tracers, rewrite `set_ftrace_filter` and event filters/triggers, and clear or inject ring-buffer records \u2014 modifying kernel-wide tracing behavior and destroying trace/audit evidence that the administrator believed was locked down.\nA:H - Retained write access to `buffer_size_kb`/per-CPU `buffer_size_kb` permits allocating enormous per-CPU ring buffers leading to memory exhaustion and OOM kills, and enabling global function/function_graph tracing degrades the entire system, so a complete denial of service is achievable."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: guard against invalid STA ID on removal
Guard against invalid station IDs in iwl_mvm_mld_rm_sta_id as that would
result in out-of-bounds array accesses. This prevents issues should the
driver get into a bad state during error handling.

The attacker only needs IP reachability to the bearer address, not link-layer adjacency.\nAC:L - The error path is entered whenever `tipc_msg_validate()` rejects the reassembled message, and every field it checks (version, header size, message size, length) lives in the attacker-supplied fragment payload, so a FIRST_FRAGMENT followed by a malformed LAST_FRAGMENT triggers the UAF deterministically. There is no race and no memory-layout condition outside the attacker\u0027s influence \u2014 skb heap grooming is done by the attacker\u0027s own packet stream.\nPR:N - TIPC neighbour discovery and link establishment (`tipc_disc_rcv` \u2192 `tipc_node_check_dest`) perform no authentication whatsoever; only a matching net_id (default 4711) is required, and TIPC_CRYPTO is a non-default option. An unauthenticated remote peer can bring up a link and immediately send the malicious fragment sequence.\nUI:N - The whole path executes in softirq/NAPI context on packet arrival with no involvement from any local user or application. No victim action of any kind is needed.\nS:U - The corruption is confined to kernel slab memory managed by the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary. Impact is standard kernel-level compromise.\nC:H - This is a use-after-free/double-free of an skb: `kfree_skb_list_reason()` dereferences the freed fragment\u0027s `next` pointer, and the freed object can be reclaimed and filled with attacker-chosen data via network skb spraying, yielding a controlled read primitive and kernel memory disclosure.\nI:H - The coalesce path double-frees the skb into `skbuff_cache`, and the frag_list path causes `__kfree_skb()` on an attacker-controlled `next` pointer \u2014 classic type-confusion/arbitrary-free primitives that are leverageable into arbitrary kernel writes and control-flow hijack.\nA:H - The flaw is a KASAN-confirmed slab use-after-free plus double free in softirq context, which reliably oopses or panics the kernel on unpatched systems. It can be re-triggered at will by an unauthenticated remote peer for a persistent remote DoS."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Init `ddp_comp` with devm_kcalloc()
In the case where `conn_routes` is true we allocate an extra slot in
the `ddp_comp` array but mtk_drm_crtc_create() never seemed to
initialize it in the test case I ran. For me, this caused a later
crash when we looped through the array in mtk_drm_crtc_mode_valid().
This showed up for me when I booted with `slub_debug=FZPUA` which
poisons the memory initially. Without `slub_debug` I couldn't
reproduce, presumably because the later code handles the value being
NULL and in most cases (not guaranteed in all cases) the memory the
allocator returned started out as 0.
It really doesn't hurt to initialize the array with devm_kcalloc()
since the array is small and the overhead of initting a handful of
elements to 0 is small. In general initting memory to zero is a safer
practice and usually it's suggested to only use the non-initting alloc
functions if you really need to.
Let's switch the function to use an allocation function that zeros the
memory. For me, this avoids the crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
epoll: be better about file lifetimes
epoll can call out to vfs_poll() with a file pointer that may race with
the last 'fput()'. That would make f_count go down to zero, and while
the ep->mtx locking means that the resulting file pointer tear-down will
be blocked until the poll returns, it means that f_count is already
dead, and any use of it won't actually get a reference to the file any
more: it's dead regardless.
Make sure we have a valid ref on the file pointer before we call down to
vfs_poll() from the epoll routines.

Kernel panic - not syncing: Fatal exception: panic_on_oops
occured when /sys/bus/ap/a[pq]mask was updated with a relative mask value
(like +0x10-0x12,+60,-90) with one of the numeric values exceeding INT_MAX.
The fix is simple: use unsigned long values for the internal variables. The
correct checks are already in place in the function but a simple int for
the internal variables was used with the possibility to overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Don't free ring buffers that couldn't be re-encrypted
In CoCo VMs it is possible for the untrusted host to cause
set_memory_encrypted() or set_memory_decrypted() to fail such that an
error is returned and the resulting memory is shared. Callers need to
take care to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional or security
issues.
The VMBus ring buffer code could free decrypted/shared pages if
set_memory_decrypted() fails. Check the decrypted field in the struct
vmbus_gpadl for the ring buffers to decide whether to free the memory.

The affected paths run automatically from driver probe/remove and channel open/close, requiring nothing from the host but its normal VMBus role.\nUI:N - The vulnerable paths execute automatically when hv_vmbus devices are probed, opened, rescinded or removed, and the host initiates the failing conversion and the teardown itself.

This is directly analogous to an IOMMU/DMA boundary bypass, where impact extends well beyond the VMBus driver\u0027s own security scope.\nC:H - Megabytes of ring-buffer pages that remain mapped shared to the host are recycled by the page allocator for arbitrary kernel and user allocations \u2014 slab objects, page cache, anonymous user pages, page tables, cryptographic keys \u2014 giving the host a persistent, continuously refreshed plaintext read window into confidential guest memory. That is a total break of the confidential VM\u0027s core confidentiality guarantee.\nI:H - The same recycled pages remain host-writable, so the host obtains an arbitrary-write primitive into whatever live kernel object currently occupies them (credentials, page tables, structures holding function pointers or list heads), which is leverageable for full control-flow hijack and kernel compromise inside the guest.\nA:H - Host writes into live kernel data occupying the recycled pages, combined with the private/shared encryption-state mismatch left by the aborted conversion (#VE / EPT violations or ciphertext garbage on subsequent private accesses), reliably produces guest memory corruption and kernel panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-pci: Check if is_avq is NULL
[bug]
In the virtio_pci_common.c function vp_del_vqs, vp_dev->is_avq is involved
to determine whether it is admin virtqueue, but this function vp_dev->is_avq
may be empty. For installations, virtio_pci_legacy does not assign a value
to vp_dev->is_avq.
[fix]
Check whether it is vp_dev->is_avq before use.
[test]
Test with virsh Attach device
Before this patch, the following command would crash the guest system
After applying the patch, everything seems to be working fine.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: walk over current view on netlink dump
The generation mask can be updated while netlink dump is in progress.
The pipapo set backend walk iterator cannot rely on it to infer what
view of the datastructure is to be used. Add notation to specify if user
wants to read/update the set.
Based on patch from Florian Westphal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-msm: pervent access to suspended controller
Generic sdhci code registers LED device and uses host->runtime_suspended
flag to protect access to it. The sdhci-msm driver doesn't set this flag,
which causes a crash when LED is accessed while controller is runtime
suspended. Fix this by setting the flag correctly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix division by zero in setup_dsc_config
When slice_height is 0, the division by slice_height in the calculation
of the number of slices will cause a division by zero driver crash. This
leaves the kernel in a state that requires a reboot. This patch adds a
check to avoid the division by zero.
The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on
a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor
connected via Thunderbolt. The amdgpu driver crashed with this exception
when I rebooted the system with the monitor connected.
kernel: ? die (arch/x86/kernel/dumpstack.c:421 arch/x86/kernel/dumpstack.c:434 arch/x86/kernel/dumpstack.c:447)
kernel: ? do_trap (arch/x86/kernel/traps.c:113 arch/x86/kernel/traps.c:154)
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu

kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: ? exc_divide_error (arch/x86/kernel/traps.c:194 (discriminator 2))
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: ? asm_exc_divide_error (./arch/x86/include/asm/idtentry.h:548)
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: dc_dsc_compute_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1109) amdgpu
After applying this patch, the driver no longer crashes when the monitor
is connected and the system is rebooted. I believe this is the same
issue reported for 3113.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset()
pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action()
fails, the irq vector is not freed, which leads to a memory leak.
Replace the devm_add_action with devm_add_action_or_reset to ensure
the irq vector can be destroyed when it fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: smbus: fix NULL function pointer dereference
Baruch reported an OOPS when using the designware controller as target
only. Target-only modes break the assumption of one transfer function
always being available. Fix this by always checking the pointer in
__i2c_transfer.
[wsa: dropped the simplification in core-smbus to avoid theoretical regressions]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix reference count leak issues of ax25_dev
The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference
count leak issue of the object "ax25_dev".
Memory leak issue in ax25_addr_ax25dev():
The reference count of the object "ax25_dev" can be increased multiple
times in ax25_addr_ax25dev(). This will cause a memory leak.
Memory leak issues in ax25_dev_device_down():
The reference count of ax25_dev is set to 1 in ax25_dev_device_up() and
then increase the reference count when ax25_dev is added to ax25_dev_list.
As a result, the reference count of ax25_dev is 2. But when the device is
shutting down. The ax25_dev_device_down() drops the reference count once
or twice depending on if we goto unlock_put or not, which will cause
memory leak.
As for the issue of ax25_addr_ax25dev(), it is impossible for one pointer
to be on a list twice. So add a break in ax25_addr_ax25dev(). As for the
issue of ax25_dev_device_down(), increase the reference count of ax25_dev
once in ax25_dev_device_up() and decrease the reference count of ax25_dev
after it is removed from the ax25_dev_list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Add a timeout to acquire the command queue semaphore
Prevent forced completion handling on an entry that has not yet been
assigned an index, causing an out of bounds access on idx = -22.
Instead of waiting indefinitely for the sem, blocking flow now waits for
index to be allocated or a sem acquisition timeout before beginning the
timer for FW completion.
Kernel log example:
mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No done completion

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fib6_rules: avoid possible NULL dereference in fib6_rule_action()
syzbot is able to trigger the following crash [1],
caused by unsafe ip6_dst_idev() use.
Indeed ip6_dst_idev() can return NULL, and must always be checked.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: i2c: et8ek8: Don't strip remove function when driver is builtin
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.
This also fixes a W=1 modpost warning:
WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)

No network or physical access is involved.\nAC:L - The missing `.remove` callback is unconditional when the driver is builtin, so cleanup is deterministically skipped on every unbind; the resulting NULL deref via the stale 0444 sysfs attribute and the dangling subdev registrations are reachable reliably with no race to win.\nPR:L - Once the driver has been unbound, an ordinary unprivileged local user reads the leftover world-readable `priv_mem` attribute or opens the still-registered `/dev/v4l-subdevX` devnode to reach the freed `et8ek8_sensor`; no capability is needed for that step, and it is not obtainable-only-as-root.\nUI:R - The dangling state only comes into existence after the driver is detached from the device (sysfs unbind, i2c adapter teardown, or DT overlay removal), which is an administrative/system action performed by someone other than the attacker.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own memory and the V4L2/media subsystem; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - The freed `sensor` remains on `mdev-\u003eentities` and the global `subdev_list`, so `MEDIA_IOC_ENUM_ENTITIES`/`G_TOPOLOGY` and subdev ioctls copy freed heap contents to userspace, and the use-after-free gives a general read primitive over reallocated kernel objects.\nI:H - The devm-freed object is still dereferenced through `sd-\u003eops` and `sd-\u003einternal_ops` function pointers on later subdev ioctls and async-notifier matching, so heap-spraying the freed allocation yields a write and control-flow hijack primitive.\nA:H - Reading the orphaned world-readable `priv_mem` sysfs file dereferences a NULL `dev_get_drvdata()` result and oopses the kernel, and the use-after-free on the still-registered subdev/media entity causes further crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Reapply "drm/qxl: simplify qxl_fence_wait"
This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
Stephen Rostedt reports:
"I went to run my tests on my VMs and the tests hung on boot up.
Unfortunately, the most I ever got out was:
[ 93.607888] Testing event system initcall: OK
[ 93.667730] Running tests on all trace events:
[ 93.669757] Testing all events: OK
[ 95.631064] ------------[ cut here ]------------
Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency
between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed"
messages again, which was the reason for that original revert. But at
this point this seems preferable to a non-booting system... ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
stm class: Fix a double free in stm_register_device()
The put_device(&stm->dev) call will trigger stm_device_release() which
frees "stm" so the vfree(stm) on the next line is a double free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix invalid unregister error path
The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL
is not defined. In that case if seg6_hmac_init() fails, the
genl_unregister_family() isn't called.
This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control
lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible
use-after-free and null-ptr-deref") replaced unregister_pernet_subsys()
with genl_unregister_family() in this error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dyndbg: fix old BUG_ON in >control parser
Fix a BUG_ON from 2009. Even if it looks "unreachable" (I didn't
really look), lets make sure by removing it, doing pr_err and return
-EINVAL instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: bcm - Fix pointer arithmetic
In spu2_dump_omd() value of ptr is increased by ciph_key_len
instead of hash_iv_len which could lead to going beyond the
buffer boundaries.
Fix this bug by changing ciph_key_len to hash_iv_len.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix peer devlink set for SF representor devlink port
The cited patch change register devlink flow, and neglect to reflect
the changes for peer devlink set logic. Peer devlink set is
triggering a call trace if done after devl_register.[1]
Hence, align peer devlink set logic with register devlink flow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential hang in nilfs_detach_log_writer()
Syzbot has reported a potential hang in nilfs_detach_log_writer() called
during nilfs2 unmount.
Analysis revealed that this is because nilfs_segctor_sync(), which
synchronizes with the log writer thread, can be called after
nilfs_segctor_destroy() terminates that thread, as shown in the call trace
below:
nilfs_detach_log_writer
nilfs_segctor_destroy
nilfs_segctor_kill_thread --> Shut down log writer thread
flush_work
nilfs_iput_work_func
nilfs_dispose_list
iput
nilfs_evict_inode
nilfs_transaction_commit
nilfs_construct_segment (if inode needs sync)
nilfs_segctor_sync --> Attempt to synchronize with
log writer thread
*** DEADLOCK ***
Fix this issue by changing nilfs_segctor_sync() so that the log writer
thread returns normally without synchronizing after it terminates, and by
forcing tasks that are already waiting to complete once after the thread
terminates.
The skipped inode metadata flushout will then be processed together in the
subsequent cleanup work in nilfs_segctor_destroy().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix incorrect list API usage
Both the function that migrates all the chunks within a region and the
function that migrates all the entries within a chunk call
list_first_entry() on the respective lists without checking that the
lists are not empty. This is incorrect usage of the API, which leads to
the following warning [1].
Fix by returning if the lists are empty as there is nothing to migrate
in this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: prevent xattr node from overflowing the eraseblock
Add a check to make sure that the requested xattr node size is no larger
than the eraseblock minus the cleanmarker.
Unlike the usual inode nodes, the xattr nodes aren't split into parts
and spread across multiple eraseblocks, which means that a xattr node
must not occupy more than one eraseblock. If the requested xattr value is
too large, the xattr node can spill onto the next eraseblock, overwriting
the nodes and causing errors such as:
jffs2: argh. node added in wrong place at 0x0000b050(2)
jffs2: nextblock 0x0000a000, expected at 0000b00c
jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050,
read=0xfc892c93, calc=0x000000
jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed
at 0x01e00c. {848f,2fc4,0fef511f,59a3d171}
jffs2: Node at 0x0000000c with length 0x00001044 would run over the
end of the erase block
jffs2: Perhaps the file system was created with the wrong erase size?
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x00000010: 0x1044 instead
This breaks the filesystem and can lead to KASAN crashes such as:
BUG: KASAN: slab-out-of-bounds in jffs2_sum_add_kvec+0x125e/0x15d0

"value": "AV:L - The vulnerability is reached through the setxattr(2)/lsetxattr/fsetxattr syscall on a file residing on an already-mounted JFFS2 volume, requiring local access to the system. There is no network-facing consumer of this path in a realistic JFFS2 (embedded flash) deployment.\nAC:L - A single setxattr call with a value larger than the eraseblock deterministically triggers the over-allocation and the overflowing write \u2014 no race, no memory-layout dependency, and the attacker chooses the value size. The only precondition is an eraseblock of 64K or less, which is the standard geometry for the NOR flash JFFS2 targets (the public reproducer used a 4K eraseblock).\nPR:L - The user.* xattr handler is registered unconditionally with CONFIG_JFFS2_FS_XATTR and the VFS only requires write permission on the target inode, so any unprivileged local account with a writable file or directory on the JFFS2 mount can reach do_jffs2_setxattr. No capability check exists anywhere on the path.\nUI:N - On the affected class of systems the JFFS2 volume is the rootfs or data partition mounted automatically at boot, so the attacker acts alone with no victim action required. The vulnerable syscall path executes entirely in the attacker\u0027s own context.\nS:U - The corruption is confined to the kernel\u0027s own memory and the flash medium it manages, within a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The wrapped write offset indexes c-\u003eblocks far out of bounds, producing a KASAN-confirmed slab out-of-bounds read and subsequent wild-pointer dereferences of attacker-groomable heap data. The corrupted on-media node layout also causes later reads to parse data at wrong offsets, exposing neighbouring nodes belonging to other users\u0027 and root-owned files.\nI:H - The oversized node is written past the end of its eraseblock, overwriting nodes of unrelated files \u2014 on a JFFS2 rootfs that means arbitrary system data an unprivileged user cannot otherwise touch. The resulting free_size underflow drives jffs2_link_node_ref() to write through a jeb-\u003elast_node pointer read from out-of-bounds heap memory, a kernel-memory write primitive suitable for control-flow hijack.\nA:H - The path reaches wild-pointer dereferences and an explicit BUG() in jffs2_link_node_ref(), panicking the kernel. Worse, the damage is persistent: the commit log shows the volume subsequently fails eraseblock scanning at mount, permanently bricking an embedded device whose rootfs is JFFS2."

The root cause is we missed to do sanity check on i_xattr_nid during
f2fs_iget(), so that in fiemap() path, current_nat_addr() will access
nat_bitmap w/ offset from invalid i_xattr_nid, result in triggering
kasan bug report, fix it.

"value": "AV:L - The vulnerable code is reached only through a locally attached/mounted crafted f2fs image, with the trigger being a local `ioctl(FS_IOC_FIEMAP, FIEMAP_FLAG_XATTR)` syscall or mount-time roll-forward recovery. No network or remote-peer data path exists into fs/f2fs/inode.c or the NAT lookup code.\nAC:L - The attacker fully controls every input \u2014 the on-disk `i_xattr_nid`, the checkpoint\u0027s NAT bitmap size, and the NAT/SSA/SIT block layout \u2014 so the out-of-range `NAT_BLOCK_OFFSET(nid)` deterministically indexes past `nm_i-\u003enat_bitmap` on the first attempt. There is no race, no dependence on uncontrollable memory layout, and no non-default kernel config (fiemap and roll-forward recovery are both default-enabled).\nPR:L - Once the image is mounted, any unprivileged user can trigger the out-of-bounds access with a plain `FS_IOC_FIEMAP` ioctl \u2014 there is no capability check anywhere on the path from `do_vfs_ioctl` through `f2fs_fiemap` to `current_nat_addr`. On Android (vold auto-mounts f2fs portable/adoptable storage) and desktop/kiosk systems (udisks2/polkit), an unprivileged console user gets the attacker\u0027s f2fs image mounted without root.\nUI:N - The attacker supplies their own crafted image and issues the fiemap ioctl themselves; removable-media auto-mount by udisks2/vold happens without any deliberate victim action. The recovery-path variant likewise fires automatically during the mount the attacker caused.\nS:U - The out-of-bounds read and the bit-flip write both stay inside the kernel\u0027s own address space and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab out-of-bounds read at an offset the attacker chooses byte-by-byte up to ~1.18 MB past a small `kmemdup`\u0027d `nat_bitmap`, so it is not a strictly bounded few-byte read. The bit read back selects which NAT block is parsed, and the resulting `ni.blk_addr` is returned to userspace as the fiemap extent\u0027s physical address, turning it into a repeatable oracle that discloses adjacent heap contents \u2014 kernel pointers and other slab objects \u2014 defeating KASLR.\nI:H - Via `f2fs_recover_xattr_data()` the bogus nid reaches `set_node_addr()`, which dirties a NAT set keyed on the out-of-range block offset; the next checkpoint then executes `f2fs_change_bit(block_off, nm_i-\u003enat_bitmap)` in `set_to_next_nat()` and `__set_bit_le(nat_index, nm_i-\u003eempty_nat_bits)` in `__update_nat_bits()` \u2014 out-of-bounds heap writes at an attacker-chosen offset. A controlled single-bit flip into a groomed adjacent slab object (pointer, refcount, or credential/permission field) is a well-established privilege-escalation primitive.\nA:H - The reported symptom is a KASAN slab-out-of-bounds report, which panics on `panic_on_warn`/hardened Android and cloud kernels; on non-KASAN kernels the read can walk into unmapped memory and oops. The out-of-bounds bit flips additionally corrupt the NAT bitmap and neighbouring heap objects, and `f2fs_bug_on`/`f2fs_handle_error` paths in the checkpoint flush stop the filesystem, so the crash is reliably re-triggerable."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix race between aio_cancel() and AIO request complete
FFS based applications can utilize the aio_cancel() callback to dequeue
pending USB requests submitted to the UDC. There is a scenario where the
FFS application issues an AIO cancel call, while the UDC is handling a
soft disconnect. For a DWC3 based implementation, the callstack looks
like the following:
DWC3 Gadget FFS Application
dwc3_gadget_soft_disconnect() ...
--> dwc3_stop_active_transfers()
--> dwc3_gadget_giveback(-ESHUTDOWN)
--> ffs_epfile_async_io_complete() ffs_aio_cancel()
--> usb_ep_free_request() --> usb_ep_dequeue()
There is currently no locking implemented between the AIO completion
handler and AIO cancel, so the issue occurs if the completion routine is
running in parallel to an AIO cancel call coming from the FFS application.
As the completion call frees the USB request (io_data->req) the FFS
application is also referencing it for the usb_ep_dequeue() call. This can
lead to accessing a stale/hanging pointer.
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")
relocated the usb_ep_free_request() into ffs_epfile_async_io_complete().
However, in order to properly implement locking to mitigate this issue, the
spinlock can't be added to ffs_epfile_async_io_complete(), as
usb_ep_dequeue() (if successfully dequeuing a USB request) will call the
function driver's completion handler in the same context. Hence, leading
into a deadlock.
Fix this issue by moving the usb_ep_free_request() back to
ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req
to NULL after freeing it within the ffs->eps_lock. This resolves the race
condition above, as the ffs_aio_cancel() routine will not continue
attempting to dequeue a request that has already been freed, or the
ffs_user_copy_work() not freeing the USB request until the AIO cancel is
done referencing it.
This fix depends on
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status
consistently")

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_fs: Fix race between aio_cancel() and AIO request complete\n\nFFS based applications can utilize the aio_cancel() callback to dequeue\npending USB requests submitted to the UDC. There is a scenario where the\nFFS application issues an AIO cancel call, while the UDC is handling a\nsoft disconnect. For a DWC3 based implementation, the callstack looks\nlike the following:\n\n DWC3 Gadget FFS Application\ndwc3_gadget_soft_disconnect() ...\n --\u003e dwc3_stop_active_transfers()\n --\u003e dwc3_gadget_giveback(-ESHUTDOWN)\n --\u003e ffs_epfile_async_io_complete() ffs_aio_cancel()\n --\u003e usb_ep_free_request() --\u003e usb_ep_dequeue()\n\nThere is currently no locking implemented between the AIO completion\nhandler and AIO cancel, so the issue occurs if the completion routine is\nrunning in parallel to an AIO cancel call coming from the FFS application.\nAs the completion call frees the USB request (io_data-\u003ereq) the FFS\napplication is also referencing it for the usb_ep_dequeue() call. This can\nlead to accessing a stale/hanging pointer.\n\ncommit b566d38857fc (\"usb: gadget: f_fs: use io_data-\u003estatus consistently\")\nrelocated the usb_ep_free_request() into ffs_epfile_async_io_complete().\nHowever, in order to properly implement locking to mitigate this issue, the\nspinlock can\u0027t be added to ffs_epfile_async_io_complete(), as\nusb_ep_dequeue() (if successfully dequeuing a USB request) will call the\nfunction driver\u0027s completion handler in the same context. Hence, leading\ninto a deadlock.\n\nFix this issue by moving the usb_ep_free_request() back to\nffs_user_copy_worker(), and ensuring that it explicitly sets io_data-\u003ereq\nto NULL after freeing it within the ffs-\u003eeps_lock. This resolves the race\ncondition above, as the ffs_aio_cancel() routine will not continue\nattempting to dequeue a request that has already been freed, or the\nffs_user_copy_work() not freeing the USB request until the AIO cancel is\ndone referencing it.\n\nThis fix depends on\n commit b566d38857fc (\"usb: gadget: f_fs: use io_data-\u003estatus\n consistently\")"

This is the gadget\u0027s userspace-facing API (f_fs), not a host-side driver parsing attacker-supplied descriptors, matching the AV:L precedent set for other gadget-side UAF races such as CVE-2024-38628.\nAC:L - The attacker controls both sides: it submits the AIO requests, triggers the bulk giveback that frees them, and then invokes `ffs_aio_cancel()` on every stale pointer at once via `free_ioctx_users()`. The ordered (max_active=1) `io_completion_wq` and the sleeping `kthread_use_mm`/`copy_to_iter` in the worker leave a huge window, and the whole sequence is freely repeatable.\nPR:L - The attacker needs an open descriptor on a functionfs endpoint file and an AIO context \u2014 available to any local unprivileged user in standard deployments, since ffs is mounted with `uid=`/`gid=`/`mode=` specifically to hand the endpoints to unprivileged daemons (adbd as `shell`, MTP as `media_rw`, embedded gadget daemons). No CAP_SYS_ADMIN is needed for the attack itself.\nUI:N - The attacking process performs every step itself \u2014 submit AIO, close ep0 to trigger the disconnect/giveback, then cancel/destroy the AIO context. No victim action is involved.\nS:U - The corruption is confined to kernel heap objects within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is standard local kernel privilege escalation.\nC:H - The use-after-free lets the attacker reclaim the freed `dwc3_request` slot with fully controlled data via the same fd (`ffs_alloc_buffer()` \u2192 `kmalloc` + `copy_from_iter_full`), after which `dwc3_gadget_ep_dequeue()`/`trace_dwc3_ep_dequeue()` dereference attacker-controlled pointers (`req-\u003edep-\u003ename`, `req-\u003etd_data-\u003estatus` on snps_udc), yielding an arbitrary kernel read primitive and leakage of adjacent heap contents.\nI:H - The stale request is passed to UDC dequeue routines that write into it and unlink it \u2014 `dwc3_gadget_giveback()` sets `req-\u003erequest.status` and `list_del()`s the entry (arbitrary write via controlled list pointers), while `snps_udc_core::udc_dequeue()` performs no membership check and calls `complete_req()`, invoking `req-\u003ereq.complete` \u2014 an indirect call through a function pointer read from freed, attacker-reclaimable memory, i.e. control-flow hijack.\nA:H - Even unweaponized, dereferencing the freed `usb_request` and the resulting double giveback/double free of `io_data` and its buffer reliably produce KASAN splats, slab corruption, and kernel panics. On a mass-disconnect the attacker triggers many of these at once with a single `io_destroy()`."

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: reliably distinguish block based and fscache mode
When erofs_kill_sb() is called in block dev based mode, s_bdev may not
have been initialised yet, and if CONFIG_EROFS_FS_ONDEMAND is enabled,
it will be mistaken for fscache mode, and then attempt to free an anon_dev
that has never been allocated, triggering the following warning:
============================================
ida_free called for id=0 which is not allocated.
WARNING: CPU: 14 PID: 926 at lib/idr.c:525 ida_free+0x134/0x140
Modules linked in:
CPU: 14 PID: 926 Comm: mount Not tainted 6.9.0-rc3-dirty #630

============================================
Now when erofs_kill_sb() is called, erofs_sb_info must have been
initialised, so use sbi->fsid to distinguish between the two modes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Avoid infinite loop trying to resize local TT
If the MTU of one of an attached interface becomes too small to transmit
the local translation table then it must be resized to fit inside all
fragments (when enabled) or a single packet.
But if the MTU becomes too low to transmit even the header + the VLAN
specific part then the resizing of the local TT will never succeed. This
can for example happen when the usable space is 110 bytes and 11 VLANs are
on top of batman-adv. In this case, at least 116 byte would be needed.
There will just be an endless spam of
batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110)
in the log but the function will never finish. Problem here is that the
timeout will be halved all the time and will then stagnate at 0 and
therefore never be able to reduce the table even more.
There are other scenarios possible with a similar result. The number of
BATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too
high to fit inside a packet. Such a scenario can therefore happen also with
only a single VLAN + 7 non-purgable addresses - requiring at least 120
bytes.
While this should be handled proactively when:
* interface with too low MTU is added
* VLAN is added
* non-purgeable local mac is added
* MTU of an attached interface is reduced
* fragmentation setting gets disabled (which most likely requires dropping
attached interfaces)
not all of these scenarios can be prevented because batman-adv is only
consuming events without the the possibility to prevent these actions
(non-purgable MAC address added, MTU of an attached interface is reduced).
It is therefore necessary to also make sure that the code is able to handle
also the situations when there were already incompatible system
configuration are present.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group
The perf tool allows users to create event groups through following
cmd [1], but the driver does not check whether the array index is out of
bounds when writing data to the event_group array. If the number of events
in an event_group is greater than HISI_PCIE_MAX_COUNTERS, the memory write
overflow of event_group array occurs.
Add array index check to fix the possible array out of bounds violation,
and return directly when write new events are written to array bounds.
There are 9 different events in an event_group.
[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}'

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: af_bluetooth: Fix deadlock
Attemting to do sock_lock on .recvmsg may cause a deadlock as shown
bellow, so instead of using sock_sock this uses sk_receive_queue.lock
on bt_sock_ioctl to avoid the UAF:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fec: remove .ndo_poll_controller to avoid deadlocks
There is a deadlock issue found in sungem driver, please refer to the
commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid
deadlocks"). The root cause of the issue is that netpoll is in atomic
context and disable_irq() is called by .ndo_poll_controller interface
of sungem driver, however, disable_irq() might sleep. After analyzing
the implementation of fec_poll_controller(), the fec driver should have
the same issue. Due to the fec driver uses NAPI for TX completions, the
.ndo_poll_controller is unnecessary to be implemented in the fec driver,
so fec_poll_controller() can be safely removed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
e1000e: change usleep_range to udelay in PHY mdic access
This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround
for sporadic MDI error on Meteor Lake systems"). The referenced commit
used usleep_range inside the PHY access routines, which are sometimes
called from an atomic context. This can lead to a kernel panic in some
scenarios, such as cable disconnection and reconnection on vPro systems.
Solve this by changing the usleep_range calls back to udelay.

RoCE is confined to a lossless L2/L3 datacenter segment rather than the open Internet, so the attacker must be on the adjacent fabric.\nAC:L - The attacker fully controls the trigger \u2014 repeatedly opening RDMA connections or issuing requests with invalid rkeys deterministically produces non-flush error CQEs, each of which emits an unratelimited KERN_ERR line plus a hex dump. No memory-layout or timing condition outside the attacker\u0027s control is involved.\nPR:N - RDMA target services (NFS/RDMA, SMB Direct, nvmet-rdma, SMC-R) accept connections from any peer on the fabric, and connection-setup/teardown transport errors occur before any application-level authentication. The alternative local path only needs an unprivileged user with the world-accessible /dev/infiniband/uverbs* device.\nUI:N - The flood is produced entirely by attacker-initiated RDMA traffic (or attacker-issued poll_cq calls); no action by any local user or administrator is needed.\nS:U - The impact \u2014 kernel log flooding, lockup/panic, and log disclosure \u2014 stays within the kernel\u0027s own security authority on the affected host; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - The KERN_ERR `print_hex_dump()` of the raw CQE exposes connection metadata \u2014 rkey/immediate data, local and remote QPN, source MAC, VLAN \u2014 to the console and dmesg, where unprivileged local readers see it when dmesg_restrict is off. The leak is real but bounded to 32/64 bytes of completion data, not arbitrary kernel memory.\nI:N - No memory corruption or data modification occurs; the change only alters log verbosity and rate.\nA:H - The commit states outright that \"too much print may lead to a panic in kernel\"; the unratelimited printk plus per-CQE hex dump executes under `spin_lock_irqsave(\u0026hr_cq-\u003elock)`, so a burst of error completions keeps a CPU with interrupts disabled writing to a slow console, producing soft/hard-lockup watchdog panics and console/log saturation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-v2: Check for non-NULL vCPU in vgic_v2_parse_attr()
vgic_v2_parse_attr() is responsible for finding the vCPU that matches
the user-provided CPUID, which (of course) may not be valid. If the ID
is invalid, kvm_get_vcpu_by_id() returns NULL, which isn't handled
gracefully.
Similar to the GICv3 uaccess flow, check that kvm_get_vcpu_by_id()
actually returns something and fail the ioctl if not.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix data races in unix_release_sock/unix_stream_sendmsg
A data-race condition has been identified in af_unix. In one data path,
the write function unix_release_sock() atomically writes to
sk->sk_shutdown using WRITE_ONCE. However, on the reader side,
unix_stream_sendmsg() does not read it atomically. Consequently, this
issue is causing the following KCSAN splat to occur:
BUG: KCSAN: data-race in unix_release_sock / unix_stream_sendmsg

value changed: 0x01 -> 0x03
The line numbers are related to commit dd5a440a31fa ("Linux 6.9-rc7").
Commit e1d09c2c2f57 ("af_unix: Fix data races around sk->sk_shutdown.")
addressed a comparable issue in the past regarding sk->sk_shutdown.
However, it overlooked resolving this particular data path.
This patch only offending unix_stream_sendmsg() function, since the
other reads seem to be protected by unix_state_lock() as discussed in

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

Per CVSS the vulnerable configuration (a \u003e4K PAGE_SIZE kernel, which is the distro default on RHEL aarch64 and ppc64le, the very hosts paired with MI100/MI200 accelerators) is assumed rather than scored as added complexity, and the attacker can trivially confirm it with getpagesize().\nPR:L - kfd_open() performs no capability check and AMDKFD_IOC_ALLOC_MEMORY_OF_GPU is registered with flags 0, so neither CAP_SYS_ADMIN nor CAP_CHECKPOINT_RESTORE is required anywhere along the path. Any local user able to open /dev/kfd \u2014 which ROCm installs expose as 0666 or to the render/video group \u2014 can perform the mapping.\nUI:N - The attacking process performs the ioctl and mmap entirely on its own file descriptor with no victim involvement. No other user needs to open a file, mount a filesystem, or run any GPU workload.\nS:U - The exposed MMIO belongs to a device managed by the same kernel that is compromised, so the vulnerable and impacted resources fall under a single security authority. This is a standard local kernel privilege-escalation primitive rather than a hypervisor or host-IOMMU boundary crossing, and the remap is disabled entirely under SR-IOV.\nC:H - Instead of a 4KB HDP-flush window, userspace obtains readable access to ~60KB of live GPU register space, and on Arcturus/Aldebaran that window contains the SDMA2\u2013SDMA7 register blocks. Control of a DMA engine\u0027s ring registers yields an arbitrary memory read primitive and permits reading other ROCm processes\u0027 or tenants\u0027 GPU memory by bypassing GPUVM isolation.\nI:H - The mapping is created with PROT_WRITE honoured via io_remap_pfn_range(), giving unprivileged userspace direct write access to DMA-engine ring base/control registers such as mmSDMA2_GFX_RB_BASE. An attacker can point an SDMA ring at attacker-authored command packets and obtain arbitrary DMA writes, escalating to full kernel compromise.\nA:H - Writing arbitrary values into the exposed SDMA/GC control registers immediately wedges the DMA engines and triggers GPU hangs, ring timeouts and device resets, and on many configurations an unrecoverable GPU reset takes down the whole graphics/compute stack. The write is unconditional and repeatable, so a trivial loop reliably denies service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/debugfs: Fix two locking issues with thermal zone debug
With the current thermal zone locking arrangement in the debugfs code,
user space can open the "mitigations" file for a thermal zone before
the zone's debugfs pointer is set which will result in a NULL pointer
dereference in tze_seq_start().
Moreover, thermal_debug_tz_remove() is not called under the thermal
zone lock, so it can run in parallel with the other functions accessing
the thermal zone's struct thermal_debugfs object. Then, it may clear
tz->debugfs after one of those functions has checked it and the
struct thermal_debugfs object may be freed prematurely.
To address the first problem, pass a pointer to the thermal zone's
struct thermal_debugfs object to debugfs_create_file() in
thermal_debug_tz_add() and make tze_seq_start(), tze_seq_next(),
tze_seq_stop(), and tze_seq_show() retrieve it from s->private
instead of a pointer to the thermal zone object. This will ensure
that tz_debugfs will be valid across the "mitigations" file accesses
until thermal_debugfs_remove_id() called by thermal_debug_tz_remove()
removes that file.
To address the second problem, use tz->lock in thermal_debug_tz_remove()
around the tz->debugfs value check (in case the same thermal zone is
removed at the same time in two different threads) and its reset to NULL.

There is no network or remote-peer data path into thermal_debugfs.c.\nAC:L - The attacker fully controls the reader side of the race and can spin on open()/read() of the mitigations file indefinitely, while zone add/remove (driver bind/unbind, module load/unload, hotplug, suspend/resume) recurs during normal operation and is directly triggerable by anyone able to unbind the thermal driver. The UAF window spans the whole episode-list teardown and the NULL-deref window spans from `tz-\u003edebugfs = NULL` until `debugfs_remove()`, so no condition outside the attacker\u0027s influence is needed.\nPR:L - Exploitation needs only a local account with read access to the thermal debugfs entry; on the embedded, Android and appliance builds where CONFIG_THERMAL_DEBUGFS is actually enabled, debugfs is routinely mounted with ownership/permissions relaxed for non-root thermal and telemetry daemons. No capability check exists in the code path itself, so a low-privileged local context is sufficient.\nUI:N - The attacker triggers the bug entirely from their own process by reading the debugfs file; no victim action, mount, or file-open by another user is required.\nS:U - The corruption and its consequences are confined to the kernel of the same host, with no crossing of a VM, IOMMU, or other security-authority boundary. This is standard in-kernel memory corruption.\nC:H - The use-after-free lets a reallocated ~576-byte slab object be walked as the `tz_episodes` list, and tze_seq_show() formats fields reached through those attacker-influenced pointers straight into the seq_file returned to userspace, giving an arbitrary-read/kernel-memory-disclosure primitive.\nI:H - After the free, mutex_lock()/mutex_unlock() and the list operations write into the freed allocation, so heap spraying gives control over adjacent/reallocated kernel objects and a write primitive usable for control-flow hijacking and privilege escalation.\nA:H - Both defects reliably crash the kernel \u2014 an unconditional mutex_lock() on a NULL tz-\u003edebugfs, and locking/list traversal of freed memory \u2014 producing an oops or panic, and the UAF can also deadlock on a destroyed mutex."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: micrel: Fix receiving the timestamp in the frame for lan8841
The blamed commit started to use the ptp workqueue to get the second
part of the timestamp. And when the port was set down, then this
workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING
is not enabled, then the ptp_clock is not initialized so then it would
crash when it would try to access the delayed work.
So then basically by setting up and then down the port, it would crash.
The fix consists in checking if the ptp_clock is initialized and only
then cancel the delayed work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix UAF for cq async event
The refcount of CQ is not protected by locks. When CQ asynchronous
events and CQ destruction are concurrent, CQ may have been released,
which will cause UAF.
Use the xa_lock() to protect the CQ refcount.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the
resp_pkts queue and then a decision is made whether to run the completer
task inline or schedule it. Finally the skb is dereferenced to bump a 'hw'
performance counter. This is wrong because if the completer task is
already running in a separate thread it may have already processed the skb
and freed it which can cause a seg fault. This has been observed
infrequently in testing at high scale.
This patch fixes this by changing the order of enqueuing the packet until
after the counter is accessed.

RoCEv2 is routable IP/UDP traffic, so the attacker is not confined to the local L2 segment.\nAC:L - The attacker controls both sides of the race: the vulnerable counter access only occurs when resp_pkts already holds another packet (queue_len \u003e 1), a condition created by bursting response packets while the completer work item concurrently drains and kfree_skb()s them on another CPU. The commit describes it triggering under high packet load, which is exactly what an attacker-driven flood produces.\nPR:N - RoCEv2 provides no authentication; the only checks before the UAF are QPN lookup, QP state, source/destination IP matching the QP\u0027s address vector, default pkey, and a plain CRC32 ICRC that any attacker can compute. A malicious or compromised RDMA peer, or an attacker spoofing the peer\u0027s source address, needs no credentials on the target system.\nUI:N - Exploitation requires only that the target have an active RC/UC queue pair in RTS state, which is the normal steady-state operating condition of an RDMA connection. No action by any local user or administrator is needed at attack time.\nS:U - The use-after-free corrupts kernel slab memory and is exploited within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed skb\u0027s control block is read after kfree_skb(), so the attacker can groom the reallocated slab object to source the rxe pointer, and a use-after-free on the skb slab is a classic primitive for leaking adjacent kernel memory and defeating KASLR.\nI:H - The stale pointer read from the freed object is immediately passed to rxe_counter_inc(), which performs atomic64_inc(\u0026rxe-\u003estats_counters[index]) \u2014 a write through an attacker-influenceable pointer, giving a targeted 64-bit increment primitive that can corrupt arbitrary kernel structures and be escalated to control-flow hijack.\nA:H - The commit explicitly reports a segmentation fault (kernel oops) from this dereference, and any unresolved use-after-free of an skb reliably crashes or panics the kernel, which a remote attacker can trigger repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal/drivers/tsens: Fix null pointer dereference
compute_intercept_slope() is called from calibrate_8960() (in tsens-8960.c)
as compute_intercept_slope(priv, p1, NULL, ONE_PT_CALIB) which lead to null
pointer dereference (if DEBUG or DYNAMIC_DEBUG set).
Fix this bug by adding null pointer check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/userfaultfd: reset ptes when close() for wr-protected ones
Userfaultfd unregister includes a step to remove wr-protect bits from all
the relevant pgtable entries, but that only covered an explicit
UFFDIO_UNREGISTER ioctl, not a close() on the userfaultfd itself. Cover
that too. This fixes a WARN trace.
The only user visible side effect is the user can observe leftover
wr-protect bits even if the user close()ed on an userfaultfd when
releasing the last reference of it. However hopefully that should be
harmless, and nothing bad should happen even if so.
This change is now more important after the recent page-table-check
patch we merged in mm-unstable (446dd9ad37d0 ("mm/page_table_check:
support userfault wr-protect entries")), as we'll do sanity check on
uffd-wp bits without vma context. So it's better if we can 100%
guarantee no uffd-wp bit leftovers, to make sure each report will be
valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe()
In the prueth_probe() function, if one of the calls to emac_phy_connect()
fails due to of_phy_connect() returning NULL, then the subsequent call to
phy_attached_info() will dereference a NULL pointer.
Check the return code of emac_phy_connect and fail cleanly if there is an
error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault()
This was missed because of the function pointer indirection.
nvidia_smmu_context_fault() is also installed as a irq function, and the
'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain
is embedded at a non-zero offset this causes nvidia_smmu_context_fault()
to miscompute the offset. Fixup the types.

No race or unpredictable precondition is involved.\nPR:L - Only ordinary local privileges are needed \u2014 a VFIO-assigned device handed to an unprivileged process or a guest VM, or a userspace-driven DMA engine on Tegra, is enough to provoke the fault; no root or CAP_SYS_ADMIN check exists on the fault-reporting path.\nUI:N - The attacker triggers the DMA fault directly; no action by any other user or administrator is required.\nS:U - The IOMMU still correctly blocks the offending DMA \u2014 the defect is in the fault-reporting handler \u2014 so both the vulnerable and impacted components are the host kernel with no crossing of a DMA or virtualization security boundary.\nC:H - The confused pointer is fetched from the adjacent heap object, and the resulting `bases[]` value is used as the base for readl/readq operations whose results (fsr, fsynr, iova, cbfrsynra) are printed to the kernel log, giving a groomable read primitive with disclosure of kernel memory contents.\nI:H - This is a type confusion in which a pointer field is taken from neighbouring heap memory and then used for register accesses including writel_relaxed(), so the kernel operates on and writes through an attacker-influenceable address.\nA:H - The dereference of the miscomputed pointer produces a fatal oops in hard IRQ context \u2014 as demonstrated by the reported NULL-pointer dereference at 0x120 on Jetson Orin NX \u2014 and can be triggered repeatedly, panicking the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: bfa: Ensure the copied buf is NUL terminated
Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul instead
of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: Fix gluebi NULL pointer dereference caused by ftl notifier
If both ftl.ko and gluebi.ko are loaded, the notifier of ftl
triggers NULL pointer dereference when trying to access
‘gluebi->desc’ in gluebi_read().
ubi_gluebi_init
ubi_register_volume_notifier
ubi_enumerate_volumes
ubi_notify_all
gluebi_notify nb->notifier_call()
gluebi_create
mtd_device_register
mtd_device_parse_register
add_mtd_device
blktrans_notify_add not->add()
ftl_add_mtd tr->add_mtd()
scan_header
mtd_read
mtd_read_oob
mtd_read_oob_std
gluebi_read mtd->read()
gluebi->desc - NULL
Detailed reproduction information available at the Link [1],
In the normal case, obtain gluebi->desc in the gluebi_get_device(),
and access gluebi->desc in the gluebi_read(). However,
gluebi_get_device() is not executed in advance in the
ftl_add_mtd() process, which leads to NULL pointer dereference.
The solution for the gluebi module is to run jffs2 on the UBI
volume without considering working with ftl or mtdblock [2].
Therefore, this problem can be avoided by preventing gluebi from
creating the mtdblock device after creating mtd partition of the
type MTD_UBIVOLUME.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix the pre-flush when appending to a file in writethrough mode
In netfs_perform_write(), when the file is marked NETFS_ICTX_WRITETHROUGH
or O_*SYNC or RWF_*SYNC was specified, write-through caching is performed
on a buffered file. When setting up for write-through, we flush any
conflicting writes in the region and wait for the write to complete,
failing if there's a write error to return.
The issue arises if we're writing at or above the EOF position because we
skip the flush and - more importantly - the wait. This becomes a problem
if there's a partial folio at the end of the file that is being written out
and we want to make a write to it too. Both the already-running write and
the write we start both want to clear the writeback mark, but whoever is
second causes a warning looking something like:
------------[ cut here ]------------
R=00000012: folio 11 is not under writeback
WARNING: CPU: 34 PID: 654 at fs/netfs/write_collect.c:105
...
CPU: 34 PID: 654 Comm: kworker/u386:27 Tainted: G S ...
...
Workqueue: events_unbound netfs_write_collection_worker
...
RIP: 0010:netfs_writeback_lookup_folio
Fix this by making the flush-and-wait unconditional. It will do nothing if
there are no folios in the pagecache and will return quickly if there are
no folios in the region specified.
Further, move the WBC attachment above the flush call as the flush is going
to attach a WBC and detach it again if it is not present - and since we
need one anyway we might as well share it.

When setting up for write-through, we flush any\nconflicting writes in the region and wait for the write to complete,\nfailing if there\u0027s a write error to return.\n\nThe issue arises if we\u0027re writing at or above the EOF position because we\nskip the flush and - more importantly - the wait. This becomes a problem\nif there\u0027s a partial folio at the end of the file that is being written out\nand we want to make a write to it too. Both the already-running write and\nthe write we start both want to clear the writeback mark, but whoever is\nsecond causes a warning looking something like:\n\n ------------[ cut here ]------------\n R=00000012: folio 11 is not under writeback\n WARNING: CPU: 34 PID: 654 at fs/netfs/write_collect.c:105\n ...\n CPU: 34 PID: 654 Comm: kworker/u386:27 Tainted: G S ...\n ...\n Workqueue: events_unbound netfs_write_collection_worker\n ...\n RIP: 0010:netfs_writeback_lookup_folio\n\nFix this by making the flush-and-wait unconditional. It will do nothing if\nthere are no folios in the pagecache and will return quickly if there are\nno folios in the region specified.\n\nFurther, move the WBC attachment above the flush call as the flush is going\nto attach a WBC and detach it again if it is not present - and since we\nneed one anyway we might as well share it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
firewire: nosy: ensure user_length is taken into account when fetching packet contents
Ensure that packet_buffer_get respects the user_length provided. If
the length of the head packet exceeds the user_length, packet_buffer_get
will now return 0 to signify to the user that no data were read
and a larger buffer size is required. Helps prevent user space overflows.

{

"value": "AV:L - The vulnerability is triggered by a local `read(2)` syscall on the `/dev/nosy` character device, where the caller supplies the undersized `user_length` that the kernel then ignores. Although the overflowing bytes originate from the IEEE 1394 bus, the vulnerable code path itself is entered and controlled entirely through a local file-descriptor operation.\nAC:L - The attacker simply calls `read()` with a small `count` while any traffic is present on the snooped 1394 bus (cycle-start packets alone arrive every 125 \u00b5s, and a bus reset queues a packet), making the overflow reliably and repeatedly reproducible with no memory-layout or timing conditions outside the attacker\u0027s control.\nPR:L - `nosy.c` contains no capability or permission checks whatsoever \u2014 reachability is decided solely by the permissions on `/dev/nosy`, which on the developer, lab, embedded and protocol-analysis systems where this sniffer is deployed is routinely opened up to a non-root group or passed into a container. Choosing the higher-severity option between L and H, an ordinary unprivileged user with the device node is sufficient.\nUI:N - The attacker performs the `read()` themselves and needs no victim action; the overflow occurs as soon as a packet longer than the supplied buffer is dequeued. No mount, no file open by another user, no configuration change by an administrator is required.\nS:U - The out-of-bounds write lands inside the address space of the process that issued the `read()`, and the compromised resources belong to the same security authority as the vulnerable kernel component. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `nosy_read()` returns a length greater than the requested `count`, so a caller following the standard read idiom consumes, prints, or logs memory located beyond its own buffer \u2014 an unbounded disclosure of adjacent process memory (heap pointers, keys, buffered data). The accompanying memory corruption is further leverageable to leak state from a privileged reader.\nI:H - Up to roughly 8 KB of externally supplied 1394 packet bytes are written past the end of the caller\u0027s stack or heap buffer, giving a large, content-controlled out-of-bounds write. Overwriting adjacent objects, saved registers, or function pointers in a nosy consumer that customarily runs as root yields control-flow hijack and arbitrary modification.\nA:H - The overflow reliably smashes adjacent memory and will SIGSEGV or abort the reading process (typically a root sniffer/logging daemon), and the copy can also fault mid-transfer leaving the buffer state inconsistent. Repeated triggering keeps the affected service permanently down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ip_tunnel: make sure to pull inner header in ip_tunnel_rcv()
Apply the same fix than ones found in :
8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
1ca1ba465e55 ("geneve: make sure to pull inner header in geneve_rx()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

A remote attacker produces the required non-linear skb deterministically by IP-fragmenting the tunnel packet so reassembly leaves the linear area ending at the inner network header.\nAC:L - The attacker fully controls the packet layout: `pskb_may_pull()`/`__pskb_pull_tail()` pull exactly the requested bytes, so a chosen fragment split reliably leaves zero linear bytes at the inner header on every packet, and for gretap/ERSPAN the `pskb_may_pull(ETH_HLEN)` in `__iptunnel_pull_header()` lands the boundary automatically.\nPR:N - GRE and IPIP/SIT have no authentication whatsoever, and `ip_tunnel_lookup()` has wildcard-remote, collect_md and fallback-device passes that match packets from any source address, so no account or credentials on the target are required.\nUI:N - Decapsulation happens automatically in softirq context on packet receipt; no action by any local user or administrator is needed beyond the tunnel already being configured and up.\nS:U - The uninitialized read and the resulting mis-handled packet stay entirely within the kernel\u0027s own security authority; no VM, IOMMU, container or sandbox boundary is crossed.\nC:L - One to two bytes of uninitialized/stale kernel memory past `skb_tail_pointer()` (heap padding or `skb_shared_info` bytes) are read, and their low ECN bits are inferable by the attacker from whether the tunneled packet is delivered or dropped \u2014 a real but strictly bounded, low-bandwidth disclosure oracle rather than arbitrary memory read.\nI:L - No out-of-bounds write is reachable because `INET_ECN_set_ce()`/`INET_ECN_set_ect1()` bounds-check against the tail pointer, but the RFC 6040 decapsulation decision \u2014 whether the congestion (CE) signal is propagated to the inner packet and whether the frame is accepted \u2014 is driven by uninitialized memory, corrupting the ECN state of legitimate decapsulated traffic.\nA:L - The read always stays inside the skb head allocation (`skb_shared_info` follows `skb-\u003eend`), so no oops or panic is reachable on a production kernel; the effect is that legitimate tunneled packets are non-deterministically dropped via the `err \u003e 1` path (`rx_frame_errors`/`rx_errors`), degrading the tunnel rather than the host."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_obj_type_get()
nft_unregister_obj() can concurrent with __nft_obj_type_get(),
and there is not any protection when iterate over nf_tables_objects
list in __nft_obj_type_get(). Therefore, there is potential data-race
of nf_tables_objects list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_objects
list in __nft_obj_type_get(), and use rcu_read_lock() in the caller
nft_obj_type_get() to protect the entire type query process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: avoid out of bounds shift
UBSAN catches undefined behavior in blk-iocost, where sometimes
iocg->delay is shifted right by a number that is too large,
resulting in undefined behavior on some architectures.
[ 186.556576] ------------[ cut here ]------------
UBSAN: shift-out-of-bounds in block/blk-iocost.c:1366:23
shift exponent 64 is too large for 64-bit type 'u64' (aka 'unsigned long long')
CPU: 16 PID: 0 Comm: swapper/16 Tainted: G S E N 6.9.0-0_fbk700_debug_rc2_kbuilder_0_gc85af715cac0 #1
Hardware name: Quanta Twin Lakes MP/Twin Lakes Passive MP, BIOS F09_3A23 12/08/2020
Call Trace:
<IRQ>
dump_stack_lvl+0x8f/0xe0
__ubsan_handle_shift_out_of_bounds+0x22c/0x280
iocg_kick_delay+0x30b/0x310
ioc_timer_fn+0x2fb/0x1f80
__run_timer_base+0x1b6/0x250
...
Avoid that undefined behavior by simply taking the
"delay = 0" branch if the shift is too large.
I am not sure what the symptoms of an undefined value
delay will be, but I suspect it could be more than a
little annoying to debug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: fix resync softlockup when bitmap size is less than array size
Is is reported that for dm-raid10, lvextend + lvchange --syncaction will
trigger following softlockup:
kernel:watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [mdX_resync:6976]
CPU: 7 PID: 3588 Comm: mdX_resync Kdump: loaded Not tainted 6.9.0-rc4-next-20240419 #1
RIP: 0010:_raw_spin_unlock_irq+0x13/0x30
Call Trace:
<TASK>
md_bitmap_start_sync+0x6b/0xf0
raid10_sync_request+0x25c/0x1b40 [raid10]
md_do_sync+0x64b/0x1020
md_thread+0xa7/0x170
kthread+0xcf/0x100
ret_from_fork+0x30/0x50
ret_from_fork_asm+0x1a/0x30
And the detailed process is as follows:
md_do_sync
j = mddev->resync_min
while (j < max_sectors)
sectors = raid10_sync_request(mddev, j, &skipped)
if (!md_bitmap_start_sync(..., &sync_blocks))
// md_bitmap_start_sync set sync_blocks to 0
return sync_blocks + sectors_skippe;
// sectors = 0;
j += sectors;
// j never change
Root cause is that commit 301867b1c168 ("md/raid10: check
slab-out-of-bounds in md_bitmap_get_counter") return early from
md_bitmap_get_counter(), without setting returned blocks.
Fix this problem by always set returned blocks from
md_bitmap_get_counter"(), as it used to be.
Noted that this patch just fix the softlockup problem in kernel, the
case that bitmap size doesn't match array size still need to be fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: carl9170: re-fix fortified-memset warning
The carl9170_tx_release() function sometimes triggers a fortified-memset
warning in my randconfig builds:
In file included from include/linux/string.h:254,
from drivers/net/wireless/ath/carl9170/tx.c:40:
In function 'fortify_memset_chk',
inlined from 'carl9170_tx_release' at drivers/net/wireless/ath/carl9170/tx.c:283:2,
inlined from 'kref_put' at include/linux/kref.h:65:3,
inlined from 'carl9170_tx_put_skb' at drivers/net/wireless/ath/carl9170/tx.c:342:9:
include/linux/fortify-string.h:493:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
493 | __write_overflow_field(p_size_field, size);
Kees previously tried to avoid this by using memset_after(), but it seems
this does not fully address the problem. I noticed that the memset_after()
here is done on a different part of the union (status) than the original
cast was from (rate_driver_data), which may confuse the compiler.
Unfortunately, the memset_after() trick does not work on driver_rates[]
because that is part of an anonymous struct, and I could not get
struct_group() to do this either. Using two separate memset() calls
on the two members does address the warning though.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/slab: make __free(kfree) accept error pointers
Currently, if an automatically freed allocation is an error pointer that
will lead to a crash. An example of this is in wm831x_gpio_dbg_show().
171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i);
172 if (IS_ERR(label)) {
173 dev_err(wm831x->dev, "Failed to duplicate label\n");
174 continue;
175 }
The auto clean up function should check for error pointers as well,
otherwise we're going to keep hitting issues like this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: uvc: use correct buffer size when parsing configfs lists
This commit fixes uvc gadget support on 32-bit platforms.
Commit 0df28607c5cb ("usb: gadget: uvc: Generalise helper functions for
reuse") introduced a helper function __uvcg_iter_item_entries() to aid
with parsing lists of items on configfs attributes stores. This function
is a generalization of another very similar function, which used a
stack-allocated temporary buffer of fixed size for each item in the list
and used the sizeof() operator to check for potential buffer overruns.
The new function was changed to allocate the now variably sized temp
buffer on heap, but wasn't properly updated to also check for max buffer
size using the computed size instead of sizeof() operator.
As a result, the maximum item size was 7 (plus null terminator) on
64-bit platforms, and 3 on 32-bit ones. While 7 is accidentally just
barely enough, 3 is definitely too small for some of UVC configfs
attributes. For example, dwFrameInteval, specified in 100ns units,
usually has 6-digit item values, e.g. 166666 for 60fps.

Summary
In the Linux kernel, the following vulnerability has been resolved:
openrisc: traps: Don't send signals to kernel mode threads
OpenRISC exception handling sends signals to user processes on floating
point exceptions and trap instructions (for debugging) among others.
There is a bug where the trap handling logic may send signals to kernel
threads, we should not send these signals to kernel threads, if that
happens we treat it as an error.
This patch adds conditions to die if the kernel receives these
exceptions in kernel mode code.

"value": "AV:L - The trigger requires executing code on the target \u2014 an `rt_sigreturn` with a crafted `sigcontext.fpu.fpcsr`, a `PTRACE_SETREGSET(NT_PRFPREG)` on an own child, or an FP instruction with `FPCSR.FPEE` set. No network or adjacent-network path reaches `arch/openrisc/kernel/traps.c`.\nAC:L - The attacker fully controls the FPCSR value written to the SPR by the kernel-mode `l.mtspr` in `RESTORE_ALL`/`_switch`, so the kernel-mode exception is raised deterministically on every attempt; there is no race and no memory-layout dependence.\nPR:L - Any unprivileged local user can do this \u2014 `sigreturn` on a self-delivered signal needs no capability, and `ptrace` of one\u0027s own child needs none either; no CAP_SYS_ADMIN or root gate exists on the path into `do_fpe_trap()`/`do_trap()`.\nUI:N - The attacking process triggers the kernel-mode exception entirely on its own via a syscall return path; no other user or victim action is involved.\nS:U - The corruption and the crash are confined to the kernel of the same machine; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - `force_sig_fault()` hands userspace a kernel text address in `si_addr` (`regs-\u003epc` of the supervisor-mode fault), and the clobbered `EPCR`/`ESR` cause the kernel to resume in supervisor mode with attacker-controlled registers and a user-controlled `r1`, from which kernel memory can be read out.\nI:H - Because the nested kernel-mode exception overwrites `EPCR`/`ESR` mid-`RESTORE_ALL`, the subsequent `l.rfe` returns into kernel code with `SR.SM` still set and the user\u0027s register file loaded, giving a supervisor-mode stack-pivot/state-corruption primitive rather than a clean fault.\nA:H - The signal is never delivered (the kernel-mode return path skips `do_work_pending`), so the faulting `mtspr` is re-executed and the exception re-fires in an unkillable supervisor-mode loop that hangs the CPU \u2014 and on the fixed kernel the same condition is a `die()`/oops."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netrom: fix possible dead-lock in nr_rt_ioctl()
syzbot loves netrom, and found a possible deadlock in nr_rt_ioctl [1]
Make sure we always acquire nr_node_list_lock before nr_node_lock(nr_node)

Summary
In the Linux kernel, the following vulnerability has been resolved:
of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma-buf/sw-sync: don't enable IRQ from sync_print_obj()
Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from
known context") by error replaced spin_unlock_irqrestore() with
spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite
sync_print_obj() is called from sync_debugfs_show(), lockdep complains
inconsistent lock state warning.
Use plain spin_{lock,unlock}() for sync_print_obj(), for
sync_debugfs_show() is already using spin_{lock,unlock}_irq().

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Convert spinlock to mutex to lock evl workqueue
drain_workqueue() cannot be called safely in a spinlocked context due to
possible task rescheduling. In the multi-task scenario, calling
queue_work() while drain_workqueue() will lead to a Call Trace as
pushing a work on a draining workqueue is not permitted in spinlocked
context.
Call Trace:

</TASK>
The current implementation uses a spinlock to protect event log workqueue
and will lead to the Call Trace due to potential task rescheduling.
To address the locking issue, convert the spinlock to mutex, allowing
the drain_workqueue() to be called in a safe mutex-locked context.
This change ensures proper synchronization when accessing the event log
workqueue, preventing potential Call Trace and improving the overall
robustness of the code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: do not WARN if iocg was already offlined
In iocg_pay_debt(), warn is triggered if 'active_list' is empty, which
is intended to confirm iocg is active when it has debt. However, warn
can be triggered during a blkcg or disk removal, if iocg_waitq_timer_fn()
is run at that time:
WARNING: CPU: 0 PID: 2344971 at block/blk-iocost.c:1402 iocg_pay_debt+0x14c/0x190
Call trace:
iocg_pay_debt+0x14c/0x190
iocg_kick_waitq+0x438/0x4c0
iocg_waitq_timer_fn+0xd8/0x130
__run_hrtimer+0x144/0x45c
__hrtimer_run_queues+0x16c/0x244
hrtimer_interrupt+0x2cc/0x7b0
The warn in this situation is meaningless. Since this iocg is being
removed, the state of the 'active_list' is irrelevant, and 'waitq_timer'
is canceled after removing 'active_list' in ioc_pd_free(), which ensures
iocg is freed after iocg_waitq_timer_fn() returns.
Therefore, add the check if iocg was already offlined to avoid warn
when removing a blkcg or disk.

Summary
In the Linux kernel, the following vulnerability has been resolved:
phonet: fix rtm_phonet_notify() skb allocation
fill_route() stores three components in the skb:
- struct rtmsg
- RTA_DST (u8)
- RTA_OIF (u32)
Therefore, rtm_phonet_notify() should use
NLMSG_ALIGN(sizeof(struct rtmsg)) +
nla_total_size(1) +
nla_total_size(4)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ecryptfs: Fix buffer size for tag 66 packet
The 'TAG 66 Packet Format' description is missing the cipher code and
checksum fields that are packed into the message packet. As a result,
the buffer allocated for the packet is 3 bytes too small and
write_tag_66_packet() will write up to 3 bytes past the end of the
buffer.
Fix this by increasing the size of the allocation so the whole packet
will always fit in the buffer.
This fixes the below kasan slab-out-of-bounds bug:
BUG: KASAN: slab-out-of-bounds in ecryptfs_generate_key_packet_set+0x7d6/0xde0

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: xmit: make sure we have at least eth header len bytes
syzbot triggered an uninit value[1] error in bridge device's xmit path
by sending a short (less than ETH_HLEN bytes) skb. To fix it check if
we can actually pull that amount instead of assuming.
Tested with dropwatch:

"value": "AV:L - `br_dev_xmit()` is the bridge device\u0027s locally-originated transmit path \u2014 remotely received frames go through `br_handle_frame`/`br_forward` and always carry a full Ethernet header, and IP routing toward a bridge always builds one via `dev_hard_header()`. Triggering it requires local injection of a sub-14-byte skb (tun write or AF_PACKET on a `hard_header_len == 0` device, plus a tc `mirred` redirect).\nAC:L - The attacker fully and deterministically controls the skb length; there is no race, no timing window, and no dependence on memory layout or victim state. Every attempt reaches the uninitialized read and the subsequent `skb_push()` leak.\nPR:L - The setup needs CAP_NET_ADMIN/CAP_NET_RAW only within a network namespace, which any unprivileged user obtains via `unshare -Urn` (create the bridge, create the tun/tunnel device, attach the tc mirred redirect, and capture leaked frames from a veth peer). No real root in the initial namespace is required.\nUI:N - The attacker performs every step \u2014 creating the devices, writing the short frame, and reading the leaked frames back \u2014 with no action by any other user or administrator.\nS:U - The uninitialized read, the malformed skb, and the resulting disclosure all stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 14 bytes of uninitialized kernel heap (skb headroom and the region past `skb-\u003etail`, which routinely holds freed packet data and kernel values) are read and then, via the unconditional `skb_push(skb, ETH_HLEN)` in `br_dev_queue_push_xmit()`, transmitted verbatim out every bridge port where the attacker captures them. The leak is repeatable at packet rate, yielding an effectively unbounded kernel memory disclosure rather than a bounded few-byte read.\nI:L - There is no out-of-bounds write primitive, but the kernel emits malformed frames whose source/destination MAC addresses are uninitialized memory, and forwarding decisions (broadcast/multicast/unicast, FDB lookup) are made on that garbage \u2014 corrupting local and peer bridge/switch forwarding state in a limited, attacker-influenced way.\nA:H - When the short skb has less than ETH_HLEN of headroom (as in the syzbot BPF-redirect reproducer), `skb_push(skb, ETH_HLEN)` in `br_dev_queue_push_xmit()` drives `skb-\u003edata` below `skb-\u003ehead` and hits `skb_under_panic()` \u2192 `BUG()`, a hard kernel panic. Additionally the resulting skb has `mac_header`/`network_header` desynchronized from `skb-\u003edata`, propagating a malformed skb into the generic xmit path (e.g. the `WARN_ONCE` in `skb_checksum_help()`, fatal under `panic_on_warn`), and the trigger can be repeated indefinitely."

Where the attacker creates the race, AC is Low.\nPR:N - The attacker is the remote SMB peer (or a network attacker able to spoof/hijack the SMB connection); no account, credential, or local privilege on the victim host is required to send the responses that trigger the deadlock.\nUI:N - Exploitation needs no victim action \u2014 the CIFS share is already mounted as a normal deployment condition (fstab/automount), and ordinary background I/O supplies the requests whose responses the attacker manipulates.\nS:U - The deadlock is confined to the kernel of the affected client machine; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The bug is purely a lock acquisition-order violation \u2014 no memory is read out of bounds, no freed object is accessed, and no data is disclosed.\nI:N - No memory corruption, out-of-bounds write, or data modification occurs; the flaw only affects the order in which two spinlocks are taken.\nA:H - An ABBA deadlock on `srv_lock`/`mid_lock` permanently wedges two CPUs spinning with preemption disabled while holding both locks, hanging all CIFS I/O and every subsequent taker of either lock, resulting in a hard lockup/panic."

</TASK>
When fallback to TCP happens early on a client socket, snd_nxt
is not yet initialized and any incoming ack will copy such value
into snd_una. If the mptcp worker (dumbly) tries mptcp-level
re-injection after such ack, that would unconditionally trigger a send
buffer cleanup using 'bad' snd_una values.
We could easily disable re-injection for fallback sockets, but such
dumb behavior already helped catching a few subtle issues and a very
low to zero impact in practice.
Instead address the issue always initializing snd_nxt (and write_seq,
for consistency) at connect time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: read txq->read_ptr under lock
If we read txq->read_ptr without lock, we can read the same
value twice, then obtain the lock, and reclaim from there
to two different places, but crucially reclaim the same
entry twice, resulting in the WARN_ONCE() a little later.
Fix that by reading txq->read_ptr under lock.

Per WiFi frame-injection guidance this is Adjacent, not Local.\nAC:L - The attacker controls both sides of the race: sustained traffic keeps TX_CMD/BA_NOTIF reclaims firing in the RX softirq path, while injected deauth/disassoc or channel-switch frames repeatedly trigger the process-context flush reclaim, and the attempt can be retried indefinitely at high rate until the unlocked read is interleaved.\nPR:N - No credentials or authentication are required \u2014 deauth/disassoc injection and rogue-AP association handling are pre-authentication, and the reclaim path is exercised by ordinary unauthenticated 802.11 traffic and management frames.\nUI:N - No victim action is needed; an active WiFi connection carrying traffic is the normal operating state, and the flush/completion interleaving happens without any user involvement.\nS:U - The corrupted TX queue state, leaked buffers and resulting crash are all confined to the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The desynchronized read_ptr lets the loop unmap DMA buffers and release skbs for TFDs the firmware still owns, leaving stale valid TFDs in the ring that the device can fetch and transmit, exposing kernel buffer contents over the air; per guidance, memory corruption leverageable for disclosure is High.\nI:H - Premature reclaim tears down DMA mappings and frees buffers still referenced by hardware TFDs, so the device can DMA into unmapped or reallocated memory, and the ring accounting itself is corrupted \u2014 a memory-corruption primitive rather than a bounded state error.\nA:H - The bug directly produces WARN_ONCE/WARN_ON splats (a panic under panic_on_warn), and the corrupted read_ptr makes iwl_txq_space() return 0 permanently, wedging the TX queue and triggering the queue-stuck watchdog/firmware restart with loss of connectivity."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix __dst_negative_advice() race
__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.
RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).
Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.
Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.
Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.
Many thanks to Clement Lecigne for tracking this issue.
This old bug became visible after the blamed commit, using UDP sockets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: core: Fix NULL module pointer assignment at card init
The commit 81033c6b584b ("ALSA: core: Warn on empty module")
introduced a WARN_ON() for a NULL module pointer passed at snd_card
object creation, and it also wraps the code around it with '#ifdef
MODULE'. This works in most cases, but the devils are always in
details. "MODULE" is defined when the target code (i.e. the sound
core) is built as a module; but this doesn't mean that the caller is
also built-in or not. Namely, when only the sound core is built-in
(CONFIG_SND=y) while the driver is a module (CONFIG_SND_USB_AUDIO=m),
the passed module pointer is ignored even if it's non-NULL, and
card->module remains as NULL. This would result in the missing module
reference up/down at the device open/close, leading to a race with the
code execution after the module removal.
For addressing the bug, move the assignment of card->module again out
of ifdef. The WARN_ON() is still wrapped with ifdef because the
module can be really NULL when all sound drivers are built-in.
Note that we keep 'ifdef MODULE' for WARN_ON(), otherwise it would
lead to a false-positive NULL module check. Admittedly it won't catch
perfectly, i.e. no check is performed when CONFIG_SND=y. But, it's no
real problem as it's only for debugging, and the condition is pretty
rare.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/cio: Ensure the copied buf is NUL terminated
Currently, we allocate a lbuf-sized kernel buffer and copy lbuf from
userspace to that buffer. Later, we use scanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using scanf. Fix this issue by using memdup_user_nul instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline
The absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness of
interrupt affinity reconfiguration via procfs. Instead, the change is
deferred until the next instance of the interrupt being triggered on the
original CPU.
When the interrupt next triggers on the original CPU, the new affinity is
enforced within __irq_move_irq(). A vector is allocated from the new CPU,
but the old vector on the original CPU remains and is not immediately
reclaimed. Instead, apicd->move_in_progress is flagged, and the reclaiming
process is delayed until the next trigger of the interrupt on the new CPU.
Upon the subsequent triggering of the interrupt on the new CPU,
irq_complete_move() adds a task to the old CPU's vector_cleanup list if it
remains online. Subsequently, the timer on the old CPU iterates over its
vector_cleanup list, reclaiming old vectors.
However, a rare scenario arises if the old CPU is outgoing before the
interrupt triggers again on the new CPU.
In that case irq_force_complete_move() is not invoked on the outgoing CPU
to reclaim the old apicd->prev_vector because the interrupt isn't currently
affine to the outgoing CPU, and irq_needs_fixup() returns false. Even
though __vector_schedule_cleanup() is later called on the new CPU, it
doesn't reclaim apicd->prev_vector; instead, it simply resets both
apicd->move_in_progress and apicd->prev_vector to 0.
As a result, the vector remains unreclaimed in vector_matrix, leading to a
CPU vector leak.
To address this issue, move the invocation of irq_force_complete_move()
before the irq_needs_fixup() call to reclaim apicd->prev_vector, if the
interrupt is currently or used to be affine to the outgoing CPU.
Additionally, reclaim the vector in __vector_schedule_cleanup() as well,
following a warning message, although theoretically it should never see
apicd->move_in_progress with apicd->prev_cpu pointing to an offline CPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Move NPIV's transport unregistration to after resource clean up
There are cases after NPIV deletion where the fabric switch still believes
the NPIV is logged into the fabric. This occurs when a vport is
unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the
fabric.
Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including
the fabric D_ID, removes the last ndlp reference and frees the ndlp rport
object. This sometimes causes the race condition where the final DA_ID and
LOGO are skipped from being sent to the fabric switch.
Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID
and LOGO are sent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: Wait unconditionally after issuing EndXfer command
Currently all controller IP/revisions except DWC3_usb3 >= 310a
wait 1ms unconditionally for ENDXFER completion when IOC is not
set. This is because DWC_usb3 controller revisions >= 3.10a
supports GUCTL2[14: Rst_actbitlater] bit which allows polling
CMDACT bit to know whether ENDXFER command is completed.
Consider a case where an IN request was queued, and parallelly
soft_disconnect was called (due to ffs_epfile_release). This
eventually calls stop_active_transfer with IOC cleared, hence
send_gadget_ep_cmd() skips waiting for CMDACT cleared during
EndXfer. For DWC3 controllers with revisions >= 310a, we don't
forcefully wait for 1ms either, and we proceed by unmapping the
requests. If ENDXFER didn't complete by this time, it leads to
SMMU faults since the controller would still be accessing those
requests.
Fix this by ensuring ENDXFER completion by adding 1ms delay in
__dwc3_stop_active_transfer() unconditionally.

A local process holding the FFS endpoint fds (or any process able to cause the FFS daemon\u0027s fds to close) drives the whole sequence via ordinary write/close syscalls.\nAC:L - The attacker controls both sides of the race: it queues the transfer (write to the ep file) and triggers the teardown (close of the ep file), and the pre-fix code performs zero wait after ENDXFER, so the window is essentially always open rather than a narrow timing fluke. The attempt is freely repeatable and the affected DWC_usb3 \u2265 3.10a IP is a common mainstream configuration.\nPR:L - Only an unprivileged local process with access to the FunctionFS endpoint files (whose ownership is set by the mount\u0027s uid=/gid= options, e.g. the adb/MTP user on Android) is needed; no root or CAP_SYS_ADMIN is required. Queuing a transfer and closing the descriptor are ordinary file operations.\nUI:N - The attacking process performs the queue and the release itself; no victim action is required. The USB cable being attached is an ambient condition of the target device (phone on a charger/PC, kiosk, embedded controller), not an interaction the attacker must induce.\nS:U - The stale DMA writes into kernel memory the controller was already granted access to, and both the vulnerable component and the impacted component are the kernel itself. No VM, IOMMU, or sandbox security boundary is crossed.\nC:H - For IN endpoints the controller keeps reading the buffer after `usb_gadget_unmap_request_by_dev()` and `kfree()`, so contents of reallocated kernel heap memory are streamed out over USB to the attached host \u2014 an arbitrary-content kernel memory disclosure. This is a use-after-free read with attacker-observable output.\nI:H - For OUT endpoints the controller continues writing host-supplied data into memory that has been DMA-unmapped and freed, giving a use-after-free write with attacker-controlled contents into reallocated kernel objects. That is a heap-spray-friendly write primitive suitable for control-flow hijacking.\nA:H - The commit reports SMMU faults from the controller accessing already-unmapped requests, which on typical SoC IOMMU configurations abort the transaction and panic or wedge the USB controller. Absent an IOMMU, the resulting freed-memory corruption reliably produces oopses and kernel panics."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq
Undefined behavior is triggered when bnxt_qplib_alloc_init_hwq is called
with hwq_attr->aux_depth != 0 and hwq_attr->aux_stride == 0.
In that case, "roundup_pow_of_two(hwq_attr->aux_stride)" gets called.
roundup_pow_of_two is documented as undefined for 0.
Fix it in the one caller that had this combination.
The undefined behavior was detected by UBSAN:
UBSAN: shift-out-of-bounds in ./include/linux/log2.h:57:13
shift exponent 64 is too large for 64-bit type 'long unsigned int'
CPU: 24 PID: 1075 Comm: (udev-worker) Not tainted 6.9.0-rc6+ #4
Hardware name: Abacus electric, s.r.o. - servis@abacus.cz Super Server/H12SSW-iN, BIOS 2.7 10/25/2023

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix use-after-free bug in cifs_debug_data_proc_show()
Skip SMB sessions that are being teared down
(e.g. @ses->ses_status == SES_EXITING) in cifs_debug_data_proc_show()
to avoid use-after-free in @ses.
This fixes the following GPF when reading from /proc/fs/cifs/DebugData
while mounting and umounting

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Do not use WQ_MEM_RECLAIM flag for workqueue
Issue reported by customer during SRIOV testing, call trace:
When both i40e and the i40iw driver are loaded, a warning
in check_flush_dependency is being triggered. This seems
to be because of the i40e driver workqueue is allocated with
the WQ_MEM_RECLAIM flag, and the i40iw one is not.
Similar error was encountered on ice too and it was fixed by
removing the flag. Do the same for i40e too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: Assign dummy when codec not specified for a DAI link
MediaTek sound card drivers are checking whether a DAI link is present
and used on a board to assign the correct parameters and this is done
by checking the codec DAI names at probe time.
If no real codec is present, assign the dummy codec to the DAI link
to avoid NULL pointer during string comparison.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries/iommu: LPAR panics during boot up with a frozen PE
At the time of LPAR boot up, partition firmware provides Open Firmware
property ibm,dma-window for the PE. This property is provided on the PCI
bus the PE is attached to.
There are execptions where the partition firmware might not provide this
property for the PE at the time of LPAR boot up. One of the scenario is
where the firmware has frozen the PE due to some error condition. This
PE is frozen for 24 hours or unless the whole system is reinitialized.
Within this time frame, if the LPAR is booted, the frozen PE will be
presented to the LPAR but ibm,dma-window property could be missing.
Today, under these circumstances, the LPAR oopses with NULL pointer
dereference, when configuring the PCI bus the PE is attached to.
BUG: Kernel NULL pointer dereference on read at 0x000000c8

Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: Fix loading 64-bit NOMMU kernels past the start of RAM
commit 3335068f8721 ("riscv: Use PUD/P4D/PGD pages for the linear
mapping") added logic to allow using RAM below the kernel load address.
However, this does not work for NOMMU, where PAGE_OFFSET is fixed to the
kernel load address. Since that range of memory corresponds to PFNs
below ARCH_PFN_OFFSET, mm initialization runs off the beginning of
mem_map and corrupts adjacent kernel memory. Fix this by restoring the
previous behavior for NOMMU kernels.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation
Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a
struct ifla_vf_vlan_info so the size of such attribute needs to be at least
of sizeof(struct ifla_vf_vlan_info) which is 14 bytes.
The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes)
which is less than sizeof(struct ifla_vf_vlan_info) so this validation
is not enough and a too small attribute might be cast to a
struct ifla_vf_vlan_info, this might result in an out of bands
read access when accessing the saved (casted) entry in ivvl.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Reload only IB representors upon lag disable/enable
On lag disable, the bond IB device along with all of its
representors are destroyed, and then the slaves' representors get reloaded.
In case the slave IB representor load fails, the eswitch error flow
unloads all representors, including ethernet representors, where the
netdevs get detached and removed from lag bond. Such flow is inaccurate
as the lag driver is not responsible for loading/unloading ethernet
representors. Furthermore, the flow described above begins by holding
lag lock to prevent bond changes during disable flow. However, when
reaching the ethernet representors detachment from lag, the lag lock is
required again, triggering the following deadlock:

Thus, upon lag enable/disable, load and unload only the IB representors
of the slaves preventing the deadlock mentioned above.
While at it, refactor the mlx5_esw_offloads_rep_load() function to have
a static helper method for its internal logic, in symmetry with the
representor unload design.

Bytes 40-65535 of 65536 are uninitialized
Memory access of size 65536 starts at ffff888045a40000
This happens, because we're copying a 'struct btrfs_data_container' back
to user-space. This btrfs_data_container is allocated in
'init_data_container()' via kvmalloc(), which does not zero-fill the
memory.
Fix this by using kvzalloc() which zeroes out the memory on allocation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: qca: fix NULL-deref on non-serdev setup
Qualcomm ROME controllers can be registered from the Bluetooth line
discipline and in this case the HCI UART serdev pointer is NULL.
Add the missing sanity check to prevent a NULL-pointer dereference when
setup() is called for a non-serdev controller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix out-of-bound access of qmi_invoke_handler()
Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence
facing below KASAN warning,
==================================================================
BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148

==================================================================
Add a dummy terminator entry at the end to assist the qmi_invoke_handler()
in traversing up to the terminator entry without accessing an
out-of-boundary index.

Combined with the garbage qmi_elem_info pointer fed to qmi_decode_message(), this yields wild kernel memory reads well beyond a few bounded bytes.\nI:H - An attacker-selected out-of-bounds slot supplies a bogus ei pointer to qmi_decode_message(), whose qmi_decode() writes elem_len * elem_size bytes at c_struct + ei-\u003eoffset \u2014 an out-of-bounds heap write \u2014 and then calls handler-\u003efn(), an indirect call through an unvalidated pointer read from out-of-bounds memory, giving a control-flow hijack primitive.\nA:H - The out-of-bounds walk can run off the end of the module mapping and the subsequent decode/indirect call through garbage pointers reliably oopses the kernel, as demonstrated by the KASAN global-out-of-bounds report in the fix commit. It is triggerable repeatedly from an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix warning during rehash
As previously explained, the rehash delayed work migrates filters from
one region to another. This is done by iterating over all chunks (all
the filters with the same priority) in the region and in each chunk
iterating over all the filters.
When the work runs out of credits it stores the current chunk and entry
as markers in the per-work context so that it would know where to resume
the migration from the next time the work is scheduled.
Upon error, the chunk marker is reset to NULL, but without resetting the
entry markers despite being relative to it. This can result in migration
being resumed from an entry that does not belong to the chunk being
migrated. In turn, this will eventually lead to a chunk being iterated
over as if it is an entry. Because of how the two structures happen to
be defined, this does not lead to KASAN splats, but to warnings such as
[1].
Fix by creating a helper that resets all the markers and call it from
all the places the currently only reset the chunk marker. For good
measures also call it when starting a completely new rehash. Add a
warning to avoid future cases.

The 5-second rehash interval and unlimited retries make this reliably reproducible.\nPR:L - tc filter installation is gated only by netlink_net_capable(CAP_NET_ADMIN) checked against the network namespace\u0027s user_ns, and mlxsw ports do not set NETIF_F_NETNS_LOCAL, so a switch port delegated into a container/tenant netns lets an otherwise unprivileged user with a user namespace reach this path. No real root in the init namespace is required.\nUI:N - The rehash delayed work runs automatically every 5 seconds by default and the attacker triggers the whole sequence with their own tc filter operations. No action by any other user is needed.\nS:U - The corruption stays within the kernel\u0027s own memory and the switch driver\u0027s data structures, all under the same security authority.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix reference count leak issue of net_device
There is a reference count leak issue of the object "net_device" in
ax25_dev_device_down(). When the ax25 device is shutting down, the
ax25_dev_device_down() drops the reference count of net_device one
or zero times depending on if we goto unlock_put or not, which will
cause memory leak.
In order to solve the above issue, decrease the reference count of
net_device after dev->ax25_ptr is set to null.

Summary
In the Linux kernel, the following vulnerability has been resolved:
maple_tree: fix mas_empty_area_rev() null pointer dereference
Currently the code calls mas_start() followed by mas_data_end() if the
maple state is MA_START, but mas_start() may return with the maple state
node == NULL. This will lead to a null pointer dereference when checking
information in the NULL node, which is done in mas_data_end().
Avoid setting the offset if there is no node by waiting until after the
maple state is checked for an empty or single entry state.
A user could trigger the events to cause a kernel oops by unmapping all
vmas to produce an empty maple tree, then mapping a vma that would cause
the scenario described above.

Summary
In the Linux kernel, the following vulnerability has been resolved:
icmp: prevent possible NULL dereferences from icmp_build_probe()
First problem is a double call to __in_dev_get_rcu(), because
the second one could return NULL.
if (__in_dev_get_rcu(dev) && __in_dev_get_rcu(dev)->ifa_list)
Second problem is a read from dev->ip6_ptr with no NULL check:
if (!list_empty(&rcu_dereference(dev->ip6_ptr)->addr_list))
Use the correct RCU API to fix these.
v2: add missing include <net/addrconf.h>

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix memory leak during rehash
The rehash delayed work migrates filters from one region to another.
This is done by iterating over all chunks (all the filters with the same
priority) in the region and in each chunk iterating over all the
filters.
If the migration fails, the code tries to migrate the filters back to
the old region. However, the rollback itself can also fail in which case
another migration will be erroneously performed. Besides the fact that
this ping pong is not a very good idea, it also creates a problem.
Each virtual chunk references two chunks: The currently used one
('vchunk->chunk') and a backup ('vchunk->chunk2'). During migration the
first holds the chunk we want to migrate filters to and the second holds
the chunk we are migrating filters from.
The code currently assumes - but does not verify - that the backup chunk
does not exist (NULL) if the currently used chunk does not reference the
target region. This assumption breaks when we are trying to rollback a
rollback, resulting in the backup chunk being overwritten and leaked
[1].
Fix by not rolling back a failed rollback and add a warning to avoid
future cases.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_acl_tcam: Fix memory leak during rehash\n\nThe rehash delayed work migrates filters from one region to another.\nThis is done by iterating over all chunks (all the filters with the same\npriority) in the region and in each chunk iterating over all the\nfilters.\n\nIf the migration fails, the code tries to migrate the filters back to\nthe old region. However, the rollback itself can also fail in which case\nanother migration will be erroneously performed. Besides the fact that\nthis ping pong is not a very good idea, it also creates a problem.\n\nEach virtual chunk references two chunks: The currently used one\n(\u0027vchunk-\u003echunk\u0027) and a backup (\u0027vchunk-\u003echunk2\u0027). During migration the\nfirst holds the chunk we want to migrate filters to and the second holds\nthe chunk we are migrating filters from.\n\nThe code currently assumes - but does not verify - that the backup chunk\ndoes not exist (NULL) if the currently used chunk does not reference the\ntarget region. This assumption breaks when we are trying to rollback a\nrollback, resulting in the backup chunk being overwritten and leaked\n[1].\n\nFix by not rolling back a failed rollback and add a warning to avoid\nfuture cases.\n\n[1]\nWARNING: CPU: 5 PID: 1063 at lib/parman.c:291 parman_destroy+0x17/0x20\nModules linked in:\nCPU: 5 PID: 1063 Comm: kworker/5:11 Tainted: G W 6.9.0-rc2-custom-00784-gc6a05c468a0b #14\nHardware name: Mellanox Technologies Ltd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: move the EST lock to struct stmmac_priv
Reinitialize the whole EST structure would also reset the mutex
lock which is embedded in the EST structure, and then trigger
the following warning. To address this, move the lock to struct
stmmac_priv. We also need to reacquire the mutex lock when doing
this initialization.

Summary
In the Linux kernel, the following vulnerability has been resolved:
um: Add winch to winch_handlers before registering winch IRQ
Registering a winch IRQ is racy, an interrupt may occur before the winch is
added to the winch_handlers list.
If that happens, register_winch_irq() adds to that list a winch that is
scheduled to be (or has already been) freed, causing a panic later in
winch_cleanup().
Avoid the race by adding the winch to the winch_handlers list before
registering the IRQ, and rolling back if um_request_irq() fails.

"value": "AV:L - The vulnerable code is UML console/tty setup reached by opening a UML console or serial device (`/dev/tty*`, `/dev/ttyS*`) inside the guest, i.e. via a local `open()` syscall. Although the `con=port:` telnet channel type can have its setup triggered by an incoming connection, the standard and reliable reach is local.\nAC:L - The attacker creates and repeats the race themselves \u2014 closing and reopening the line clears `line-\u003esigio` and re-runs `register_winch_irq()`, so the tiny window between `um_request_irq()` and `list_add()` can be attacked in an unbounded retry loop. Once the early interrupt lands, the freed object stays linked in the global `winch_handlers` list deterministically, and the later dereference is delayed long enough for reliable heap grooming.\nPR:L - No capability or credential check exists anywhere on the path from `open()` through `line_open()` \u2192 `line_activate()` \u2192 `register_winch_irq()`; only device-node permissions gate it, and a plain unprivileged guest user is sufficient both to open a console/serial line and to spray the `kmalloc-96` slab that reclaims the freed `struct winch`.\nUI:N - Winch registration happens automatically when a configured console line is first opened (including at boot), and the attacker can drive that open themselves. No action by any other user is required.\nS:U - The corruption and its impact are confined to the UML kernel\u0027s own memory and the process it already fully controls, which is standard in-kernel privilege escalation. No hypervisor, IOMMU, or sandbox authority boundary is crossed by the vulnerable component.\nC:H - This is a use-after-free on a small, easily reclaimed slab object; the later walk of `winch_handlers` calls `tty_port_tty_get(winch-\u003eport)` on an attacker-controlled pointer, giving an arbitrary-dereference read primitive usable to disclose kernel memory.\nI:H - The stale `list_add()` writes two pointers into freed (reclaimable) memory, and the later `free_winch()` performs `free_stack(winch-\u003estack, 0)` on an attacker-controlled address plus a double `kfree()` and `os_kill_process(winch-\u003epid, 1)`, yielding write/free primitives suitable for control-flow hijack.\nA:H - The commit itself states the dangling list entry causes a panic in `winch_cleanup()`, and any use-after-free of this kind reliably produces an oops or kernel panic in the UML instance."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix netdev refcount issue
The dev_tracker is added to ax25_cb in ax25_bind(). When the
ax25 device is detaching, the dev_tracker of ax25_cb should be
deallocated in ax25_kill_by_device() instead of the dev_tracker
of ax25_dev. The log reported by ref_tracker is shown below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered
The power_supply frame-work is not really designed for there to be
long living in kernel references to power_supply devices.
Specifically unregistering a power_supply while some other code has
a reference to it triggers a WARN in power_supply_unregister():
WARN_ON(atomic_dec_return(&psy->use_cnt));
Folllowed by the power_supply still getting removed and the
backing data freed anyway, leaving the tusb1210 charger-detect code
with a dangling reference, resulting in a crash the next time
tusb1210_get_online() is called.
Fix this by only holding the reference in tusb1210_get_online()
freeing it at the end of the function. Note this still leaves
a theoretical race window, but it avoids the issue when manually
rmmod-ing the charger chip driver during development.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
to bug_table entries, and as a result the last entry in a bug table will
be ignored, potentially leading to an unexpected panic(). All prior
entries in the table will be handled correctly.
The arm64 ABI requires that struct fields of up to 8 bytes are
naturally-aligned, with padding added within a struct such that struct
are suitably aligned within arrays.
When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
signed int file_disp; // 4 bytes
unsigned short line; // 2 bytes
unsigned short flags; // 2 bytes
}
... with 12 bytes total, requiring 4-byte alignment.
When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 2 bytes
}
... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
padding, requiring 4-byte alginment.
When we create a bug_entry in assembly, we align the start of the entry
to 4 bytes, which implicitly handles padding for any prior entries.
However, we do not align the end of the entry, and so when
CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
bytes.
For the main kernel image this is not a problem as find_bug() doesn't
depend on the trailing padding bytes when searching for entries:
for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
if (bugaddr == bug_addr(bug))
return bug;
However for modules, module_bug_finalize() depends on the trailing
bytes when calculating the number of entries:
mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
... and as the last bug_entry lacks the necessary padding bytes, this entry
will not be counted, e.g. in the case of a single entry:
sechdrs[i].sh_size == 6
sizeof(struct bug_entry) == 8;
sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
Consequently module_find_bug() will miss the last bug_entry when it does:
for (i = 0; i < mod->num_bugs; ++i, ++bug)
if (bugaddr == bug_addr(bug))
goto out;
... which can lead to a kenrel panic due to an unhandled bug.
This can be demonstrated with the following module:
static int __init buginit(void)
{
WARN(1, "hello\n");
return 0;
}
static void __exit bugexit(void)
{
}
module_init(buginit);
module_exit(bugexit);
MODULE_LICENSE("GPL");
... which will trigger a kernel panic when loaded:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.

Both sides of the race are driven by local syscalls (close() generating TIME-WAIT, connect() reusing the 4-tuple), fully exercisable over loopback.\nAC:L - The attacker creates and controls both sides of the race \u2014 one set of threads generates TIME-WAIT sockets via active close, another loops on bind()+connect() against the same 4-tuple \u2014 and can retry indefinitely at thousands of attempts per second, as demonstrated by the reporter\u0027s working `trigger` reproducer. No non-default sysctl is required, since the explicitly-bound `twp == NULL` path bypasses the `tcp_tw_reuse` check entirely.\nPR:L - Only an unprivileged local user account is needed: creating TCP sockets, bind() with SO_REUSEADDR, connect(), and close() require no capabilities, and the whole sequence works inside a network namespace or on loopback.\nUI:N - The attacker performs every step itself with its own sockets; no victim action or interaction of any kind is needed.\nS:U - The corruption is confined to kernel slab memory managed by the same security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The refcount underflow prematurely frees a `tcp_timewait_sock` that is still referenced by the ehash/bhash chains and the connect path; on a SLAB_TYPESAFE_BY_RCU slab the attacker reallocates that memory with sprayed TIME-WAIT sockets, yielding a use-after-free read primitive over kernel memory and adjacent socket state.\nI:H - The stale pointers permit writes through the dangling object \u2014 hlist_nulls chain pointer updates, timer re-arming, and `inet_twsk_kill()` refcount decrements applied to reallocated objects \u2014 cascading into refcount corruption of unrelated `struct sock` allocations, a well-established path to arbitrary write and control-flow hijack.\nA:H - Even the benign outcome is a `refcount_t` WARN (an immediate panic under the widely used panic_on_warn), and the underflow reliably frees a live socket, causing kernel oops/panic from list-corruption and freed-memory dereference in the TCP hash tables."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, skmsg: Fix NULL pointer dereference in sk_psock_skb_ingress_enqueue
Fix NULL pointer data-races in sk_psock_skb_ingress_enqueue() which
syzbot reported [1].

Reported by Kernel Concurrency Sanitizer on:
CPU: 0 PID: 10713 Comm: syz-executor.4 Tainted: G W 6.8.0-syzkaller-08951-gfe46a7dd189e #0
Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 02/29/2024
Prior to this, commit 4cd12c6065df ("bpf, sockmap: Fix NULL pointer
dereference in sk_psock_verdict_data_ready()") fixed one NULL pointer
similarly due to no protection of saved_data_ready. Here is another
different caller causing the same issue because of the same reason. So
we should protect it with sk_callback_lock read lock because the writer
side in the sk_psock_drop() uses "write_lock_bh(&sk->sk_callback_lock);".
To avoid errors that could happen in future, I move those two pairs of
lock into the sk_psock_data_ready(), which is suggested by John Fastabend.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: once more fix the call oder in amdgpu_ttm_move() v2
This reverts drm/amdgpu: fix ftrace event amdgpu_bo_move always move
on same heap. The basic problem here is that after the move the old
location is simply not available any more.
Some fixes were suggested, but essentially we should call the move
notification before actually moving things because only this way we have
the correct order for DMA-buf and VM move notifications as well.
Also rework the statistic handling so that we don't update the eviction
counter before the move.
v2: add missing NULL check

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix out-of-bounds access in ops_init
net_alloc_generic is called by net_alloc, which is called without any
locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It
is read twice, first to allocate an array, then to set s.len, which is
later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is
registering a new pernet ops, increments max_gen_ptrs, which is then used
to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If
max_gen_ptrs is later incremented, it will be caught in net_assign_generic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi/unaccepted: touch soft lockup during memory accept
Commit 50e782a86c98 ("efi/unaccepted: Fix soft lockups caused by
parallel memory acceptance") has released the spinlock so other CPUs can
do memory acceptance in parallel and not triggers softlockup on other
CPUs.
However the softlock up was intermittent shown up if the memory of the
TD guest is large, and the timeout of softlockup is set to 1 second:
RIP: 0010:_raw_spin_unlock_irqrestore
Call Trace:
? __hrtimer_run_queues
<IRQ>
? hrtimer_interrupt
? watchdog_timer_fn
? __sysvec_apic_timer_interrupt

exc_page_fault
? __do_huge_pmd_anonymous_page
asm_exc_page_fault
__handle_mm_fault
When the local irq is enabled at the end of accept_memory(), the
softlockup detects that the watchdog on single CPU has not been fed for
a while. That is to say, even other CPUs will not be blocked by
spinlock, the current CPU might be stunk with local irq disabled for a
while, which hurts not only nmi watchdog but also softlockup.
Chao Gao pointed out that the memory accept could be time costly and
there was similar report before. Thus to avoid any softlocup detection
during this stage, give the softlockup a flag to skip the timeout check
at the end of accept_memory(), by invoking touch_softlockup_watchdog().
