Summary
A denial-of-service vulnerability exists in github.com/sirupsen/logrus when using Entry.Writer() to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read fails with "token too long" and the writer pipe is closed, leaving Writer() unusable and causing application unavailability (DoS). This affects versions < 1.8.3, 1.9.0, and 1.9.2. The issue is fixed in 1.8.3, 1.9.1, and 1.9.3+, where the input is chunked and the writer continues to function even if an error is logged.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: ensure no dirty metadata is written back for an fs with errors
[BUG]
During development of a minor feature (make sure all btrfs_bio::end_io()
is called in task context), I noticed a crash in generic/388, where
metadata writes triggered new works after btrfs_stop_all_workers().
It turns out that it can even happen without any code modification, just
using RAID5 for metadata and the same workload from generic/388 is going
to trigger the use-after-free.
[CAUSE]
If btrfs hits an error, the fs is marked as error, no new
transaction is allowed thus metadata is in a frozen state.
But there are some metadata modifications before that error, and they are
still in the btree inode page cache.
Since there will be no real transaction commit, all those dirty folios
are just kept as is in the page cache, and they can not be invalidated
by invalidate_inode_pages2() call inside close_ctree(), because they are
dirty.
And finally after btrfs_stop_all_workers(), we call iput() on btree
inode, which triggers writeback of those dirty metadata.
And if the fs is using RAID56 metadata, this will trigger RMW and queue
new works into rmw_workers, which is already stopped, causing warning
from queue_work() and use-after-free.
[FIX]
Add a special handling for write_one_eb(), that if the fs is already in
an error state, immediately mark the bbio as failure, instead of really
submitting them.
Then during close_ctree(), iput() will just discard all those dirty
tree blocks without really writing them back, thus no more new jobs for
already stopped-and-freed workqueues.
The extra discard in write_one_eb() also acts as an extra safenet.
E.g. the transaction abort is triggered by some extent/free space
tree corruptions, and since extent/free space tree is already corrupted
some tree blocks may be allocated where they shouldn't be (overwriting
existing tree blocks). In that case writing them back will further
corrupting the fs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: bitblit: bound-check glyph index in bit_putcs*
bit_putcs_aligned()/unaligned() derived the glyph pointer from the
character value masked by 0xff/0x1ff, which may exceed the actual font's
glyph count and read past the end of the built-in font array.
Clamp the index to the actual glyph count before computing the address.
This fixes a global out-of-bounds read reported by syzbot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Fix use-after-free in tipc_mon_reinit_self().
syzbot reported use-after-free of tipc_net(net)->monitors[]
in tipc_mon_reinit_self(). [0]
The array is protected by RTNL, but tipc_mon_reinit_self()
iterates over it without RTNL.
tipc_mon_reinit_self() is called from tipc_net_finalize(),
which is always under RTNL except for tipc_net_finalize_work().
Let's hold RTNL in tipc_net_finalize_work().

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Add bounds checking in bit_putcs to fix vmalloc-out-of-bounds
Add bounds checking to prevent writes past framebuffer boundaries when
rendering text near screen edges. Return early if the Y position is off-screen
and clip image height to screen boundary. Break from the rendering loop if the
X position is off-screen. When clipping image width to fit the screen, update
the character count to match the clipped width to prevent buffer size
mismatches.
Without the character count update, bit_putcs_aligned and bit_putcs_unaligned
receive mismatched parameters where the buffer is allocated for the clipped
width but cnt reflects the original larger count, causing out-of-bounds writes.

There is no remote or network-reachable path into fbcon\u0027s glyph blitting.\nAC:L - The reproducer is deterministic \u2014 an ioctl puts the VC geometry out of sync with the framebuffer resolution and the very next console redraw performs the out-of-bounds write; syzbot produced a reliable reproducer and confirmed the fix. No race, no memory-layout luck, and no unusual configuration is required (fbcon with DRM fbdev emulation is the default on ordinary systems).\nPR:L - No capability check exists anywhere on the path: `fbcon_set_con2fb_map_ioctl()` and the `FBIOPUT_CON2FBMAP`/`FBIOPUT_VSCREENINFO` handlers perform no `capable()` test, and the VT resize/mode ioctls only require being the owner of the controlling tty. Any unprivileged local user holding the usual graphics/console device access (group `video`, logind uaccess ACLs, Android/kiosk/embedded graphics processes) can reach it.\nUI:N - The attacker performs every step themselves \u2014 issue the ioctl to desynchronize the console geometry, then write bytes to their own console fd to force the redraw. No victim action or interaction is needed.\nS:U - The corruption occurs in kernel virtual memory and is exploited to escalate within the same kernel security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The bug yields an out-of-bounds write with an attacker-influenced offset into the vmalloc region, adjacent to other DRM GEM shmem vmapped buffers and kernel objects, which is readily leveraged into arbitrary kernel memory disclosure (e.g. by corrupting neighbouring buffer pointers/lengths or other clients\u0027 graphics buffers that the attacker can mmap).\nI:H - This is a controlled out-of-bounds write: the destination offset is derived from attacker-set VC geometry and font metrics, and the written content is attacker-chosen (console text rendered through a user-supplied font via KDFONTOP), giving a powerful kernel write primitive suitable for privilege escalation.\nA:H - The out-of-bounds write past the vmalloc\u0027d framebuffer corrupts adjacent kernel memory or hits an unmapped guard page, producing a KASAN-confirmed vmalloc-out-of-bounds write and, in production kernels, an oops/panic that can be triggered repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential overflow of PCM transfer buffer
The PCM stream data in USB-audio driver is transferred over USB URB
packet buffers, and each packet size is determined dynamically. The
packet sizes are limited by some factors such as wMaxPacketSize USB
descriptor. OTOH, in the current code, the actually used packet sizes
are determined only by the rate and the PPS, which may be bigger than
the size limit above. This results in a buffer overflow, as reported
by syzbot.
Basically when the limit is smaller than the calculated packet size,
it implies that something is wrong, most likely a weird USB
descriptor. So the best option would be just to return an error at
the parameter setup time before doing any further operations.
This patch introduces such a sanity check, and returns -EINVAL when
the packet size is greater than maxpacksize. The comparison with
ep->packsize[1] alone should suffice since it's always equal or
greater than ep->packsize[0].

Although a malformed descriptor is one way to reach it, no physical interaction is required for a local attacker on a machine with an attached USB audio device.\nAC:L - The attacker deterministically chooses the rate and sample format that make `packsize[1] * stride` exceed the `wMaxPacketSize`-derived buffer, then triggers the copy by starting playback \u2014 no race, no memory-layout guessing, and the condition is fully reproducible on every URB submission.\nPR:L - Only access to the ALSA PCM device node is required, which is granted to the logged-in session user via logind ACLs or membership in the `audio` group; no CAP_SYS_ADMIN or root is needed.\nUI:N - The attacking process performs open/hw_params/prepare/write entirely on its own; no victim action is needed, and on desktop/Android systems PipeWire/AudioFlinger will even drive the stream automatically on hotplug.\nS:U - The corruption stays within the kernel\u0027s own memory and the USB host controller\u0027s DMA-coherent pool, managed by the same security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The oversized `iso_frame_desc` lengths cause the host controller to DMA kernel memory beyond the allocated coherent buffer out to the USB device, disclosing adjacent kernel heap contents to the attacker; heap corruption can also be leveraged for broader arbitrary read.\nI:H - `copy_to_urb()` memcpy\u0027s an attacker-controlled length of attacker-controlled PCM bytes past the end of the coherent URB buffer, giving a heap out-of-bounds write with controlled content \u2014 a primitive suitable for corrupting adjacent objects and hijacking control flow.\nA:H - Overrunning the DMA-coherent transfer buffer corrupts neighbouring kernel/DMA-pool memory and reliably produces an oops or panic, as observed in the syzbot report and the related bugzilla crash reports."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: bcsp: receive data only if registered
Currently, bcsp_recv() can be called even when the BCSP protocol has not
been registered. This leads to a NULL pointer dereference, as shown in
the following stack trace:
KASAN: null-ptr-deref in range [0x0000000000000108-0x000000000000010f]
RIP: 0010:bcsp_recv+0x13d/0x1740 drivers/bluetooth/hci_bcsp.c:590

To prevent this, ensure that the HCI_UART_REGISTERED flag is set before
processing received data. If the protocol is not registered, return
-EUNATCH.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix crash while sending Action Frames in standalone AP Mode
Currently, whenever there is a need to transmit an Action frame,
the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to
firmware. The P2P interfaces were available when wpa_supplicant is managing
the wlan interface.
However, the P2P interfaces are not created/initialized when only hostapd
is managing the wlan interface. And if hostapd receives an ANQP Query REQ
Action frame even from an un-associated STA, the brcmfmac driver tries
to use an uninitialized P2P vif pointer for sending the IOVAR to firmware.
This NULL pointer dereferencing triggers a driver crash.

[ 1417.076589] Code: f9401e80 aa1603e2 f9403be1 5280e483 (f9400000)
Fix this, by always using the vif corresponding to the wdev on which the
Action frame Transmission request was initiated by the userspace. This way,
even if P2P vif is not available, the IOVAR is sent to firmware on AP vif
and the ANQP Query RESP Action frame is transmitted without crashing the
driver.
Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev()
to brcmf_p2p_attach(). Because the former function would not get executed
when only hostapd is managing wlan interface, and it is not safe to do
reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior
init_completion().
And in the brcmf_p2p_tx_action_frame() function, the condition check for
P2P Presence response frame is not needed, since the wpa_supplicant is
properly sending the P2P Presense Response frame on the P2P-GO vif instead
of the P2P-Device vif.

Summary
In the Linux kernel, the following vulnerability has been resolved:
9p/trans_fd: p9_fd_request: kick rx thread if EPOLLIN
p9_read_work() doesn't set Rworksched and doesn't do schedule_work(m->rq)
if list_empty(&m->req_list).
However, if the pipe is full, we need to read more data and this used to
work prior to commit aaec5a95d59615 ("pipe_read: don't wake up the writer
if the pipe is still full").
p9_read_work() does p9_fd_read() -> ... -> anon_pipe_read() which (before
the commit above) triggered the unnecessary wakeup. This wakeup calls
p9_pollwake() which kicks p9_poll_workfn() -> p9_poll_mux(), p9_poll_mux()
will notice EPOLLIN and schedule_work(&m->rq).
This no longer happens after the optimization above, change p9_fd_request()
to use p9_poll_mux() instead of only checking for EPOLLOUT.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: cancel mesh send timer when hdev removed
mesh_send_done timer is not canceled when hdev is removed, which causes
crash if the timer triggers after hdev is gone.
Cancel the timer when MGMT removes the hdev, like other MGMT timers.
Should fix the BUG: sporadically seen by BlueZ test bot
(in "Mesh - Send cancel - 1" test).

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: fix use-after-free due to MST port state bypass
syzbot reported[1] a use-after-free when deleting an expired fdb. It is
due to a race condition between learning still happening and a port being
deleted, after all its fdbs have been flushed. The port's state has been
toggled to disabled so no learning should happen at that time, but if we
have MST enabled, it will bypass the port's state, that together with VLAN
filtering disabled can lead to fdb learning at a time when it shouldn't
happen while the port is being deleted. VLAN filtering must be disabled
because we flush the port VLANs when it's being deleted which will stop
learning. This fix adds a check for the port's vlan group which is
initialized to NULL when the port is getting deleted, that avoids the port
state bypass. When MST is enabled there would be a minimal new overhead
in the fast-path because the port's vlan group pointer is cache-hot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_badd
In snd_usb_create_streams(), for UAC version 3 devices, the Interface
Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this
call fails, a fallback routine attempts to obtain the IAD from the next
interface and sets a BADD profile. However, snd_usb_mixer_controls_badd()
assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,
without performing a NULL check. This can lead to a NULL pointer
dereference when usb_ifnum_to_if() fails to find the interface descriptor.
This patch adds a NULL pointer check after calling usb_ifnum_to_if() in
snd_usb_mixer_controls_badd() to prevent the dereference.
This issue was discovered by syzkaller, which triggered the bug by sending
a crafted USB device descriptor.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/secretmem: fix use-after-free race in fault handler
When a page fault occurs in a secret memory file created with
`memfd_secret(2)`, the kernel will allocate a new folio for it, mark the
underlying page as not-present in the direct map, and add it to the file
mapping.
If two tasks cause a fault in the same page concurrently, both could end
up allocating a folio and removing the page from the direct map, but only
one would succeed in adding the folio to the file mapping. The task that
failed undoes the effects of its attempt by (a) freeing the folio again
and (b) putting the page back into the direct map. However, by doing
these two operations in this order, the page becomes available to the
allocator again before it is placed back in the direct mapping.
If another task attempts to allocate the page between (a) and (b), and the
kernel tries to access it via the direct map, it would result in a
supervisor not-present page fault.
Fix the ordering to restore the direct map before the folio is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto
syzbot reported a possible shift-out-of-bounds [1]
Blamed commit added rto_alpha_max and rto_beta_max set to 1000.
It is unclear if some sctp users are setting very large rto_alpha
and/or rto_beta.
In order to prevent user regression, perform the test at run time.
Also add READ_ONCE() annotations as sysctl values can change under us.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: client: fix memory leak in smb3_fs_context_parse_param
The user calls fsconfig twice, but when the program exits, free() only
frees ctx->source for the second fsconfig, not the first.
Regarding fc->source, there is no code in the fs context related to its
memory reclamation.
To fix this memory leak, release the source memory corresponding to ctx
or fc before each parsing.
syzbot reported:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: free copynotify stateid in nfs4_free_ol_stateid()
Typically copynotify stateid is freed either when parent's stateid
is being close/freed or in nfsd4_laundromat if the stateid hasn't
been used in a lease period.
However, in case when the server got an OPEN (which created
a parent stateid), followed by a COPY_NOTIFY using that stateid,
followed by a client reboot. New client instance while doing
CREATE_SESSION would force expire previous state of this client.
It leads to the open state being freed thru release_openowner->
nfs4_free_ol_stateid() and it finds that it still has copynotify
stateid associated with it. We currently print a warning and is
triggerred
WARNING: CPU: 1 PID: 8858 at fs/nfsd/nfs4state.c:1550 nfs4_free_ol_stateid+0xb0/0x100 [nfsd]
This patch, instead, frees the associated copynotify stateid here.
If the parent stateid is freed (without freeing the copynotify
stateids associated with it), it leads to the list corruption
when laundromat ends up freeing the copynotify state later.

There is no network or remote path into the command verifier.\nAC:L - The attacker fully and deterministically controls header-\u003esize in the command stream they submit; setting it to 0xFFFFFFF8..0xFFFFFFFF reliably wraps the 32-bit size computation and bypasses the size_remaining check every time. No race, timing window, or uncontrollable precondition is involved.\nPR:L - VMW_EXECBUF is declared DRM_RENDER_ALLOW and vmwgfx sets DRIVER_RENDER, so no DRM master or authentication is needed \u2014 any unprivileged local user with access to the render node (standard for graphics/desktop users and containers in VMware guests) can submit commands.\nUI:N - The attacker triggers the flaw entirely on their own by issuing the execbuf ioctl with a crafted SVGA3D command header. No victim action or interaction is required.\nS:U - The integer overflow and the resulting out-of-bounds accesses occur within the guest kernel\u0027s own address space and are confined to the kernel\u0027s security authority. No hypervisor, IOMMU, or sandbox boundary is crossed by the kernel-side defect itself.\nC:H - The unchecked header-\u003esize drives pointer arithmetic in vmw_cmd_dma(), vmw_cmd_draw(), and vmw_cmd_tex_state(), producing large out-of-bounds reads of adjacent kernel memory whose contents are interpreted as resource handles; success/failure of vmw_user_resource_lookup_handle() forms a scanning oracle over kernel heap contents, so arbitrary kernel memory disclosure is achievable.\nI:H - The same overflow yields out-of-bounds writes \u2014 vmw_cmd_dma() writes bo_size into suffix-\u003emaximumOffset past the buffer, and OOB-derived relocation offsets cause vmw_resource_relocations_apply() to write 32-bit resource IDs outside the command buffer. Controlled heap corruption of this kind is a standard path to privilege escalation.\nA:H - A header-\u003esize of 0xFFFFFFF8 makes *size zero, causing vmw_cmd_check_all() to spin forever while holding dev_priv-\u003ecmdbuf_mutex, and the far out-of-bounds reads past a vmalloc\u0027d bounce buffer hit a guard page and oops the kernel. Either outcome is a full denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_connmark: initialize struct tc_ife to fix kernel leak
In tcf_connmark_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF
There is a KASAN: slab-use-after-free read in btusb_disconnect().
Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will
free the btusb data associated with the interface. The same data is
then used later in the function, hence the UAF.
Fix by moving the accesses to btusb data to before the data is free'd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/habanalabs: support mapping cb with vmalloc-backed coherent memory
When IOMMU is enabled, dma_alloc_coherent() with GFP_USER may return
addresses from the vmalloc range. If such an address is mapped without
VM_MIXEDMAP, vm_insert_page() will trigger a BUG_ON due to the
VM_PFNMAP restriction.
Fix this by checking for vmalloc addresses and setting VM_MIXEDMAP
in the VMA before mapping. This ensures safe mapping and avoids kernel
crashes. The memory is still driver-allocated and cannot be accessed
directly by userspace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devices
Previously, APU platforms (and other scenarios with uninitialized VRAM managers)
triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The root
cause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,
but that `man->bdev` (the backing device pointer within the manager) remains
uninitialized (NULL) on APUs—since APUs lack dedicated VRAM and do not fully
set up VRAM manager structures. When `ttm_resource_manager_usage()` attempts to
acquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading to
a kernel OOPS.
1. **amdgpu_cs.c**: Extend the existing bandwidth control check in
`amdgpu_cs_get_threshold_for_moves()` to include a check for
`ttm_resource_manager_used()`. If the manager is not used (uninitialized
`bdev`), return 0 for migration thresholds immediately—skipping VRAM-specific
logic that would trigger the NULL dereference.
2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info
reporting to use a conditional: if the manager is used, return the real VRAM
usage; otherwise, return 0. This avoids accessing `man->bdev` when it is
NULL.
3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function)
data write path. Use `ttm_resource_manager_used()` to check validity: if the
manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set
`fb_usage` to 0 (APUs have no discrete framebuffer to report).
This approach is more robust than APU-specific checks because it:
- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),
- Aligns with TTM's design by using its native helper function,
- Preserves correct behavior for discrete GPUs (which have fully initialized
`man->bdev` and pass the `ttm_resource_manager_used()` check).
v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-net: fix received length check in big packets
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: validate skb length for unknown CC opcode
In hci_cmd_complete_evt(), if the command complete event has an unknown
opcode, we assume the first byte of the remaining skb->data contains the
return status. However, parameter data has previously been pulled in
hci_event_func(), which may leave the skb empty. If so, using skb->data[0]
for the return status uses un-init memory.
The fix is to check skb->len before using skb->data.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix improper check of dentry.stream.valid_size
We found an infinite loop bug in the exFAT file system that can lead to a
Denial-of-Service (DoS) condition. When a dentry in an exFAT filesystem is
malformed, the following system calls — SYS_openat, SYS_ftruncate, and
SYS_pwrite64 — can cause the kernel to hang.
Root cause analysis shows that the size validation code in exfat_find()
does not check whether dentry.stream.valid_size is negative. As a result,
the system calls mentioned above can succeed and eventually trigger the DoS
issue.
This patch adds a check for negative dentry.stream.valid_size to prevent
this vulnerability.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Sync pending IRQ work before freeing ring buffer
Fix a race where irq_work can be queued in bpf_ringbuf_commit()
but the ring buffer is freed before the work executes.
In the syzbot reproducer, a BPF program attached to sched_switch
triggers bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer
is freed before this work executes, the irq_work thread may accesses
freed memory.
Calling `irq_work_sync(&rb->work)` ensures that all pending irq_work
complete before freeing the buffer.

On PREEMPT_RT the work is deferred to the `irq_workd` kthread and on architectures without `arch_irq_work_has_interrupt()` to the next tick, widening the window to milliseconds; syzbot both reproduced the bug and confirmed the fix.\nPR:L - `BPF_MAP_TYPE_RINGBUF`/`USER_RINGBUF` are listed as unprivileged map types in `map_create()`, the ringbuf helpers sit above the `CAP_BPF` gate in `bpf_base_func_proto()`, `BPF_PROG_TYPE_SOCKET_FILTER` is exempt from the CAP_BPF prog-load check, and `SO_ATTACH_BPF` has no capability check \u2014 so an ordinary unprivileged user can build the entire chain on the upstream default `unprivileged_bpf_disabled=0`.\nUI:N - The attacker performs every step himself \u2014 map creation, program load, socket attach, packet injection, and fd close \u2014 with no victim action or cooperating process required.\nS:U - The use-after-free corrupts kernel memory and the per-CPU irq_work list within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `irq_work_single()` and `bpf_ringbuf_notify()`/`wake_up_all()` read `work-\u003enode.llist`, `work-\u003efunc`, `work-\u003eirqwait.task`, and the `waitq` list head out of freed memory, and the vmalloc VA range can be reclaimed with a large vmalloc-backed `BPF_MAP_TYPE_ARRAY` whose contents the attacker sets \u2014 turning the dangling traversal into an arbitrary kernel-memory read/disclosure primitive.\nI:H - The irq_work core performs `atomic_set()`/`atomic_cmpxchg()` writes into the freed object and an indirect call `work-\u003efunc(work)` on a pointer read from it, while `wake_up_all()` adds `list_del_init()` unlink writes and a second function-pointer call \u2014 after VA-range reclamation with controlled data this is a direct control-flow hijack and arbitrary-write path to privilege escalation.\nA:H - This is a use-after-free reported by syzbot as a KASAN splat; in the common case the irq_work dereferences an already-unmapped vmalloc address from hardirq or the `irq_workd` kthread, producing an unhandled page fault and kernel panic, and it can be re-triggered in a loop."

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbcon: Set fb_display[i]->mode to NULL when the mode is released
Recently, we discovered the following issue through syzkaller:
BUG: KASAN: slab-use-after-free in fb_mode_is_equal+0x285/0x2f0
Read of size 4 at addr ff11000001b3c69c by task syz.xxx
...

Based on experimentation and analysis, during framebuffer unregistration,
only the memory of fb_info->modelist is freed, without setting the
corresponding fb_display[i]->mode to NULL for the freed modes. This leads
to UAF issues during subsequent accesses. Here's an example of reproduction
steps:
1. With /dev/fb0 already registered in the system, load a kernel module
to register a new device /dev/fb1;
2. Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);
3. Switch console from fb to VGA (to allow normal rmmod of the ko);
4. Unload the kernel module, at this point fb1's modelist is freed, leaving
a wild pointer in fb_display[];
5. Trigger the bug via system calls through fb0 attempting to delete a mode
from fb0.
Add a check in do_unregister_framebuffer(): if the mode to be freed exists
in fb_display[], set the corresponding mode pointer to NULL.

The attacker can additionally groom the freed `fb_modelist` slab with controlled allocations before dereferencing it.\nPR:L - No capability check exists anywhere in the fbdev ioctl path \u2014 access is governed solely by DAC on `/dev/fbN`, which logged-in seat users obtain via logind `uaccess` ACLs or `video`/`graphics` group membership on desktops, kiosks, embedded devices and Android. An unprivileged local user with a console/seat can issue every ioctl involved.\nUI:N - The attacker performs all steps himself via ioctls on the framebuffer device; no victim action is needed. The framebuffer unregistration that creates the stale pointer occurs through ordinary system events such as USB display/dock removal or DRM driver unbind.\nS:U - The corruption and its consequences are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free reads a freed slab object that the attacker can reallocate with chosen or sensitive kernel data, and `display_to_var()`/`fb_videomode_to_var()` copy ~15 fields out of it into `info-\u003evar`, which is then readable from userspace via `FBIOGET_VSCREENINFO` \u2014 a repeatable kernel heap disclosure primitive.\nI:H - A use-after-free on a groomable kmalloc object permits heap spraying and type confusion with the reallocated victim object; the freed contents also propagate into `fb_check_var`/`fb_set_par` and console resize arithmetic, corrupting kernel state and enabling escalation to control-flow hijack.\nA:H - The reported syzkaller report is a KASAN slab-use-after-free that oopses the task in `fb_mode_is_equal()`; dereferencing the dangling pointer after the slab page is returned to the page allocator produces a kernel panic, and the stale pointer can be re-triggered repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: 6lowpan: reset link-local header on ipv6 recv path
Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local
header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW
Add missing skb_reset_mac_header() for uncompressed ipv6 RX path.
For the compressed one, it is done in lowpan_header_decompress().
Log: (BlueZ 6lowpan-tester Client Recv Raw - Success)

In the parse_adv_monitor_pattern() function, the value of
the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
The size of the 'value' array in the mgmt_adv_pattern structure is 31.
If the value of 'pattern[i].length' is set in the user space
and exceeds 31, the 'patterns[i].value' array can be accessed
out of bound when copied.
Increasing the size of the 'value' array in
the 'mgmt_adv_pattern' structure will break the userspace.
Considering this, and to avoid OOB access revert the limits for 'offset'
and 'length' back to the value of HCI_MAX_AD_LENGTH.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.
