Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: fix ordering of qlen adjustment
Changes to sch->q.qlen around qdisc_tree_reduce_backlog() need to happen
_before_ a call to said function because otherwise it may fail to notify
parent qdiscs when the child is about to become empty.

There is no remote or network data path into `exfat_create_upcase_table()`.\nAC:L - The attacker deterministically forces the first free by crafting an upcase-table dentry with a bad checksum, and can drive the required `kvcalloc` failure by generating memory/vmalloc pressure while repeatedly re-mounting the image, so success is not gated on conditions outside their influence. Consistent with prior kernel CNA scoring of allocation-failure-dependent bugs, this is Low.\nPR:L - exfat is the standard removable-media filesystem on Android and desktop Linux, where vold and udisks2 auto-mount attacker-supplied SD cards and USB sticks on behalf of the unprivileged seat/session user, so no elevated credentials are needed to reach `exfat_fill_super`. This matches the Low value assigned to the other exfat mount-time image-parsing CVEs.\nUI:N - On auto-mounting systems the crafted volume is parsed by the kernel as soon as the attacker attaches the media, and a local user with removable-media or loop-mount rights performs the entire sequence from their own process. No separate victim action is required.\nS:U - The freed `sbi-\u003evol_utbl` allocation and the resulting corruption are entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The second `kvfree()` occurs in an RCU callback long after the first, so the 128 KiB region can be reallocated to an unrelated kernel object that is then released while still referenced, giving the attacker a page/vmap-level use-after-free usable as an arbitrary kernel-memory read primitive. Double-free-class corruption is scored High.\nI:H - Freeing memory that has already been reassigned lets the attacker spray controlled data into pages or vmap areas still in use by other subsystems (kernel stacks, BPF allocations, slab metadata), yielding a write primitive and control-flow hijack potential. This is full memory corruption, not a benign accounting error.\nA:H - Even without exploitation, the double free triggers a page-allocator/vfree corruption `BUG`/`WARN` in an RCU callback context or corrupts freelists, producing a kernel oops or panic. With `panic_on_warn` set, the \"Trying to vfree() nonexistent vm area\" path is an immediate full system panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Fix a UAF vulnerability in class handling
This patch fixes a Use-After-Free vulnerability in the HFSC qdisc class
handling. The issue occurs due to a time-of-check/time-of-use condition
in hfsc_change_class() when working with certain child qdiscs like netem
or codel.
The vulnerability works as follows:
1. hfsc_change_class() checks if a class has packets (q.qlen != 0)
2. It then calls qdisc_peek_len(), which for certain qdiscs (e.g.,
codel, netem) might drop packets and empty the queue
3. The code continues assuming the queue is still non-empty, adding
the class to vttree
4. This breaks HFSC scheduler assumptions that only non-empty classes
are in vttree
5. Later, when the class is destroyed, this can lead to a Use-After-Free
The fix adds a second queue length check after qdisc_peek_len() to verify
the queue wasn't emptied.

It then calls qdisc_peek_len(), which for certain qdiscs (e.g.,\n codel, netem) might drop packets and empty the queue\n3. The code continues assuming the queue is still non-empty, adding\n the class to vttree\n4. This breaks HFSC scheduler assumptions that only non-empty classes\n are in vttree\n5.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Ignore multiple conn complete events
When one of the three connection complete events is received multiple
times for the same handle, the device is registered multiple times which
leads to memory corruptions. Therefore, consequent events for a single
connection are ignored.
The conn->state can hold different values, therefore HCI_CONN_HANDLE_UNSET
is introduced to identify new connections. To make sure the events do not
contain this or another invalid handle HCI_CONN_HANDLE_MAX and checks
are introduced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: allow exp not to be removed in nf_ct_find_expectation
Currently nf_conntrack_in() calling nf_ct_find_expectation() will
remove the exp from the hash table. However, in some scenario, we
expect the exp not to be removed when the created ct will not be
confirmed, like in OVS and TC conntrack in the following patches.
This patch allows exp not to be removed by setting IPS_CONFIRMED
in the status of the tmpl.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: avoid putting the realm twice when decoding snaps fails
When decoding the snaps fails it maybe leaving the 'first_realm'
and 'realm' pointing to the same snaprealm memory. And then it'll
put it twice and could cause random use-after-free, BUG_ON, etc
issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to
collect elements from anonymous sets with timeouts while it is being
released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x
with a pipapo set with low timeouts which is not possible upstream since
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set
element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc
in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on
transaction abort"), Florian plans to accelerate abort path by releasing
objects via workqueue, therefore, this sets on the dead flag for abort
path too.

Per kernel scoring guidance, netfilter/nftables netlink paths are Local.\nAC:L - The attacker controls both sides of the race: they create the anonymous meter set, choose the element timeouts that drive the async rhashtable GC worker (which fires every HZ since anonymous sets force gc_int=0), and choose exactly when to issue the rule-delete transaction that unbinds and asynchronously destroys the set. Failed attempts are harmless and the sequence can be repeated indefinitely with many parallel meter sets, so the race is reliably winnable.\nPR:L - The nftables netlink path only checks netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the owning user namespace of the network namespace, so an unprivileged user obtains it with `unshare -Urn` and nf_tables is fully per-netns. No real root in the initial namespace is needed.\nUI:N - The entire sequence \u2014 creating the meter rule, generating traffic to populate the set, and deleting the rule \u2014 is performed by the attacker\u0027s own process. No victim action of any kind is involved.\nS:U - The use-after-free and double-free occur in kernel heap memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is a standard kernel-local privilege escalation primitive.\nC:H - The freed nft_rhash_elem objects carry attacker-sized and attacker-controlled key/data, so the UAF permits reallocating the freed slab object with adjacent kernel data and reading it back through set-element dumps (NFT_MSG_GETSETELEM), yielding arbitrary kernel memory disclosure. Per guidance, any use-after-free is scored High.\nI:H - The concurrent GC removal and rhashtable_free_and_destroy() teardown produce a use-after-free and double-free of slab objects whose size and contents the attacker chooses, a well-established nftables heap-corruption primitive (as in CVE-2023-32233 and CVE-2024-1086) that can be groomed into an arbitrary write and full local privilege escalation.\nA:H - Even without successful exploitation, the UAF/double-free on set elements and the destroyed rhashtable bucket table causes slab corruption, list corruption, and kernel oops/panic. Any kernel crash is scored High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/packet: fix a race in packet_set_ring() and packet_notifier()
When packet_set_ring() releases po->bind_lock, another thread can
run packet_notifier() and process an NETDEV_UP event.
This race and the fix are both similar to that of commit 15fe076edea7
("net/packet: fix a race in packet_bind() and packet_notifier()").
There too the packet_notifier NETDEV_UP event managed to run while a
po->bind_lock critical section had to be temporarily released. And
the fix was similarly to temporarily set po->num to zero to keep
the socket unhooked until the lock is retaken.
The po->bind_lock in packet_set_ring and packet_notifier precede the
introduction of git history.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Do not allow binding to VMADDR_PORT_ANY
It is possible for a vsock to autobind to VMADDR_PORT_ANY. This can
cause a use-after-free when a connection is made to the bound socket.
The socket returned by accept() also has port VMADDR_PORT_ANY but is not
on the list of unbound sockets. Binding it will result in an extra
refcount decrement similar to the one fixed in fcdd2242c023 (vsock: Keep
the binding until socket destruction).
Modify the check in __vsock_bind_connectible() to also prevent binding
to VMADDR_PORT_ANY.

Summary
In the Linux kernel, the following vulnerability has been resolved:
calipso: Fix null-ptr-deref in calipso_req_{set,del}attr().
syzkaller reported a null-ptr-deref in sock_omalloc() while allocating
a CALIPSO option. [0]
The NULL is of struct sock, which was fetched by sk_to_full_sk() in
calipso_req_setattr().
Since commit a1a5344ddbe8 ("tcp: avoid two atomic ops for syncookies"),
reqsk->rsk_listener could be NULL when SYN Cookie is returned to its
client, as hinted by the leading SYN Cookie log.
Here are 3 options to fix the bug:
1) Return 0 in calipso_req_setattr()
2) Return an error in calipso_req_setattr()
3) Alaways set rsk_listener
1) is no go as it bypasses LSM, but 2) effectively disables SYN Cookie
for CALIPSO. 3) is also no go as there have been many efforts to reduce
atomic ops and make TCP robust against DDoS. See also commit 3b24d854cb35
("tcp/dccp: do not touch listener sk_refcnt under synflood").
As of the blamed commit, SYN Cookie already did not need refcounting,
and no one has stumbled on the bug for 9 years, so no CALIPSO user will
care about SYN Cookie.
Let's return an error in calipso_req_setattr() and calipso_req_delattr()
in the SYN Cookie case.
This can be reproduced by [1] on Fedora and now connect() of nc times out.
[0]:
TCP: request_sock_TCPv6: Possible SYN flooding on port [::]:20002. Sending cookies.

See also commit 3b24d854cb35\n(\"tcp/dccp: do not touch listener sk_refcnt under synflood\").\n\nAs of the blamed commit, SYN Cookie already did not need refcounting,\nand no one has stumbled on the bug for 9 years, so no CALIPSO user will\ncare about SYN Cookie.\n\nLet\u0027s return an error in calipso_req_setattr() and calipso_req_delattr()\nin the SYN Cookie case.\n\nThis can be reproduced by [1] on Fedora and now connect() of nc times out.\n\n[0]:\nTCP: request_sock_TCPv6: Possible SYN flooding on port [::]:20002.

CALIPSO labeled networking exists specifically to carry labels between remote peers over routed IPv6, so any remote host that can reach the listening port can trigger it.\nAC:L - The only precondition beyond sending SYNs is that SYN cookies be active, and the attacker creates that condition themselves by SYN-flooding the listener until `inet_csk_reqsk_queue_is_full()` (default `tcp_syncookies=1`), or it is permanently on with `=2`. No race, no memory-layout dependency, no information the attacker must first obtain \u2014 the oops reproduces deterministically on every cookie-mode SYN.\nPR:N - The vulnerable code runs inside `tcp_conn_request()` while handling the very first packet of a connection, long before any TCP handshake completes or any application-level authentication occurs. The attacker needs no account, credentials, or socket on the target.\nUI:N - Processing happens in the softirq receive path with no involvement of any local user or process. Merely having an IPv6 TCP listener with a CALIPSO NetLabel mapping is enough.\nS:U - The fault is a kernel dereference handled within the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:N - `sock_kmalloc(NULL, ...)` faults on a read of a fixed low offset (~0x30) off a NULL pointer that the attacker cannot displace or control, and the faulting value is never returned to the attacker. No memory contents are disclosed.\nI:N - The bug is a NULL-pointer read that aborts before any store; the subsequent writes (`memset(opt2,...)`, `xchg`, `atomic_sub`) are never reached because the allocation faults first. There is no out-of-bounds or freed-object write and hence no control-flow or data corruption primitive.\nA:H - The NULL dereference occurs in NAPI/softirq context, where the resulting oops is a fatal exception in interrupt context and panics the machine \u2014 the reporter\u0027s reproducer shows a GPF taking down the kernel. An unauthenticated remote attacker can repeat it at will, giving complete loss of availability."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_set_pipapo: fix initial map fill
The initial buffer has to be inited to all-ones, but it must restrict
it to the size of the first field, not the total field size.
After each round in the map search step, the result and the fill map
are swapped, so if we have a set where f->bsize of the first element
is smaller than m->bsize_max, those one-bits are leaked into future
rounds result map.
This makes pipapo find an incorrect matching results for sets where
first field size is not the largest.
Followup patch adds a test case to nft_concat_range.sh selftest script.
Thanks to Stefano Brivio for pointing out that we need to zero out
the remainder explicitly, only correcting memset() argument isn't enough.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT
In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed
to be either root or ingress. This assumption is bogus since it's valid
to create egress qdiscs with major handle ffff:
Budimir Markovic found that for qdiscs like DRR that maintain an active
class list, it will cause a UAF with a dangling class pointer.
In 066a3b5b2346, the concern was to avoid iterating over the ingress
qdisc since its parent is itself. The proper fix is to stop when parent
TC_H_ROOT is reached because the only way to retrieve ingress is when a
hierarchy which does not contain a ffff: major handle call into
qdisc_lookup with TC_H_MAJ(TC_H_ROOT).
In the scenario where major ffff: is an egress qdisc in any of the tree
levels, the updates will also propagate to TC_H_ROOT, which then the
iteration must stop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_hash - fix double free in hash_accept
If accept(2) is called on socket type algif_hash with
MSG_MORE flag set and crypto_ahash_import fails,
sk2 is freed. However, it is also freed in af_alg_release,
leading to slab-use-after-free error.

not protected by RCU read-critical region, when idr_for_each() calls
radix_tree_node_free() through call_rcu() to free the radix_tree_node
structure, the node will be freed immediately, and when reading the next
node in radix_tree_for_each_slot(), the already freed memory may be read.
Therefore, we need to add code to make sure that idr_for_each() is
protected within the RCU read-critical region when we call it in
shm_destroy_orphaned().

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: adapt set backend to use GC transaction API
Use the GC transaction API to replace the old and buggy gc API and the
busy mark approach.
No set elements are removed from async garbage collection anymore,
instead the _DEAD bit is set on so the set element is not visible from
lookup path anymore. Async GC enqueues transaction work that might be
aborted and retried later.
rbtree and pipapo set backends does not set on the _DEAD bit from the
sync GC path since this runs in control plane path where mutex is held.
In this case, set elements are deactivated, removed and then released
via RCU callback, sync GC never fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/pkey: Prevent overflow in size calculation for memdup_user()
Number of apqn target list entries contained in 'nr_apqns' variable is
determined by userspace via an ioctl call so the result of the product in
calculation of size passed to memdup_user() may overflow.
In this case the actual size of the allocated area and the value
describing it won't be in sync leading to various types of unpredictable
behaviour later.
Use a proper memdup_array_user() helper which returns an error if an
overflow is detected. Note that it is different from when nr_apqns is
initially zero - that case is considered valid and should be handled in
subsequent pkey_handler implementations.
Found by Linux Verification Center (linuxtesting.org).

"value": "AV:L - The vulnerable code is reached only through ioctl calls on the /dev/pkey misc device node; there is no network, adjacent-network, or remote-peer data path into `_copy_apqns_from_user()`. The in-kernel API (`pkey_key2protkey`) and sysfs paths always pass a NULL apqn list with count 0.\nAC:L - `apqn_entries` is a plain u32 field copied directly from the ioctl argument struct, so the attacker sets the value outright in a single deterministic ioctl call. No race, no memory-layout dependency, and no condition outside the attacker\u0027s control.\nPR:L - The pkey miscdevice is registered with `.mode = 0666`, making it world read/write, and neither `pkey_unlocked_ioctl()` nor any of the four reachable sub-handlers performs a `capable()` or `CAP_*` check. Any local unprivileged user on an s390 system with CONFIG_PKEY enabled (standard in distro mainframe kernels) can trigger it.\nUI:N - The attacker issues the ioctl directly from their own process; no victim action, mount, or file open by another user is involved.\nS:U - The undersized allocation and the resulting out-of-bounds access are both in kernel heap memory within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The size/count desynchronization causes the CCA handlers to walk `apqns[i]` far past the end of an attacker-sized kmalloc buffer, an unbounded slab out-of-bounds read rather than a few-byte overread. The disclosed heap contents are consumed as card/domain selectors, exposing adjacent kernel object data.\nI:L - All handler signatures take `const struct pkey_apqn *apqns`, so the desynchronized buffer is only ever read \u2014 there is no out-of-bounds write or control-flow hijack primitive. Integrity impact is limited to out-of-bounds heap values steering crypto-adapter requests to attacker-uncontrolled card/domain pairs.\nA:H - Iterating up to billions of entries past a small kmalloc\u0027d buffer reliably reaches unmapped memory, producing a kernel oops/panic, and the loop contains no `cond_resched()` so it can also stall the CPU. Any unprivileged local user can repeat this at will."
