Title
usb: usbtmc: Flush anchored URBs in usbtmc_release
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: usbtmc: Flush anchored URBs in usbtmc_release
When calling usbtmc_release, pending anchored URBs must be flushed or
killed to prevent use-after-free errors (e.g. in the HCD giveback
path). Call usbtmc_draw_down() to allow anchored URBs to be completed.

The attacker can open the file, issue the async operation, and cause release themselves.\nS:U - The corruption occurs within kernel USB/driver memory and affects the same kernel security authority. This is standard kernel memory corruption, not a VM, IOMMU, or sandbox boundary escape by itself.\nC:H - This is a use-after-free of per-file kernel state containing embedded USB anchors and callback context. Per the kernel scoring guidance, UAF memory corruption can be leveraged for high-impact information disclosure.\nI:H - The HCD giveback path and completion callbacks write through freed file_data/anchor memory, giving a heap corruption primitive. UAF corruption is defensibly scored as high integrity impact because it can support arbitrary write or control-flow exploitation.\nA:H - Syzbot reproduced a KASAN slab-use-after-free write in the USB giveback path after usbtmc_release freed the object.

Title
bpf: Fix incorrect pruning due to atomic fetch precision tracking
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix incorrect pruning due to atomic fetch precision tracking
When backtrack_insn encounters a BPF_STX instruction with BPF_ATOMIC
and BPF_FETCH, the src register (or r0 for BPF_CMPXCHG) also acts as
a destination, thus receiving the old value from the memory location.
The current backtracking logic does not account for this. It treats
atomic fetch operations the same as regular stores where the src
register is only an input. This leads the backtrack_insn to fail to
propagate precision to the stack location, which is then not marked
as precise!
Later, the verifier's path pruning can incorrectly consider two states
equivalent when they differ in terms of stack state. Meaning, two
branches can be treated as equivalent and thus get pruned when they
should not be seen as such.
Fix it as follows: Extend the BPF_LDX handling in backtrack_insn to
also cover atomic fetch operations via is_atomic_fetch_insn() helper.
When the fetch dst register is being tracked for precision, clear it,
and propagate precision over to the stack slot. For non-stack memory,
the precision walk stops at the atomic instruction, same as regular
BPF_LDX. This covers all fetch variants.
Before:
0: (b7) r1 = 8 ; R1=8
1: (7b) *(u64 *)(r10 -8) = r1 ; R1=8 R10=fp0 fp-8=8
2: (b7) r2 = 0 ; R2=0
3: (db) r2 = atomic64_fetch_add((u64 *)(r10 -8), r2) ; R2=8 R10=fp0 fp-8=mmmmmmmm
4: (bf) r3 = r10 ; R3=fp0 R10=fp0
5: (0f) r3 += r2

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix incorrect pruning due to atomic fetch precision tracking\n\nWhen backtrack_insn encounters a BPF_STX instruction with BPF_ATOMIC\nand BPF_FETCH, the src register (or r0 for BPF_CMPXCHG) also acts as\na destination, thus receiving the old value from the memory location.\n\nThe current backtracking logic does not account for this. It treats\natomic fetch operations the same as regular stores where the src\nregister is only an input. This leads the backtrack_insn to fail to\npropagate precision to the stack location, which is then not marked\nas precise!\n\nLater, the verifier\u0027s path pruning can incorrectly consider two states\nequivalent when they differ in terms of stack state. Meaning, two\nbranches can be treated as equivalent and thus get pruned when they\nshould not be seen as such.\n\nFix it as follows: Extend the BPF_LDX handling in backtrack_insn to\nalso cover atomic fetch operations via is_atomic_fetch_insn() helper.\nWhen the fetch dst register is being tracked for precision, clear it,\nand propagate precision over to the stack slot. For non-stack memory,\nthe precision walk stops at the atomic instruction, same as regular\nBPF_LDX.

Title
net/mlx5: Fix switchdev mode rollback in case of failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix switchdev mode rollback in case of failure
If for some internal reason switchdev mode fails, we rollback to legacy
mode, before this patch, rollback will unregister the uplink netdev and
leave it unregistered causing the below kernel bug.
To fix this, we need to avoid netdev unregister by setting the proper
rollback flag 'MLX5_PRIV_FLAGS_SWITCH_LEGACY' to indicate legacy mode.

Title
net/mlx5: lag: Check for LAG device before creating debugfs
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: lag: Check for LAG device before creating debugfs
__mlx5_lag_dev_add_mdev() may return 0 (success) even when an error
occurs that is handled gracefully. Consequently, the initialization
flow proceeds to call mlx5_ldev_add_debugfs() even when there is no
valid LAG context.
mlx5_ldev_add_debugfs() blindly created the debugfs directory and
attributes. This exposed interfaces (like the members file) that rely on
a valid ldev pointer, leading to potential NULL pointer dereferences if
accessed when ldev is NULL.
Add a check to verify that mlx5_lag_dev(dev) returns a valid pointer
before attempting to create the debugfs entries.

Title
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Oskar Kjos reported the following problem.
ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was written
by the IPv6 receive path as struct inet6_skb_parm. icmp_send() passes
IPCB(skb2) to __ip_options_echo(), which interprets that cb[] region
as struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoff
at offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr
value. __ip_options_echo() then reads optlen from attacker-controlled
packet data at sptr[rr+1] and copies that many bytes into dopt->__data,
a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).
To fix this we clear skb2->cb[], as suggested by Oskar Kjos.
Also add minimal IPv4 header validation (version == 4, ihl >= 5).
Severity
9.8 (Critical)
8.8 (High)
CWE

The layouts differ: inet6_skb_parm.nhoff\nat offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr\nvalue. __ip_options_echo() then reads optlen from attacker-controlled\npacket data at sptr[rr+1] and copies that many bytes into dopt-\u003e__data,\na fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).\n\nTo fix this we clear skb2-\u003ecb[], as suggested by Oskar Kjos.\n\nAlso add minimal IPv4 header validation (version == 4, ihl \u003e= 5)."

The vulnerable code processes network packet contents in the kernel network stack.\nAC:L - Triggering is deterministic once an IPv4-over-IPv6 tunnel endpoint exists: the attacker controls the ICMPv6 error, IPv6 extension-header-derived control block state, and quoted inner IPv4 bytes used by `__ip_options_echo()`. There is no race or hard-to-influence condition.\nPR:N - The exploit packet is unauthenticated network input and does not require the attacker to have an account or capabilities on the target. Tunnel configuration requires administration, but exploitation of an already deployed tunnel endpoint does not.\nUI:N - No victim user action is required; receipt and processing of the crafted ICMPv6 packet is enough. The path is normal kernel packet handling.\nS:U - The corruption occurs inside the kernel network stack and impacts the same kernel security authority. This is not a VM escape or cross-scope boundary bypass.\nC:H - The bug is an attacker-controlled kernel stack buffer overflow in `__ip_options_echo()` via a bogus IPv4 option length copied into a fixed 40-byte buffer. Kernel memory corruption of this kind can plausibly be leveraged for high-impact information disclosure.\nI:H - The overflow copies attacker-controlled packet data onto the kernel stack and can plausibly corrupt control data or adjacent state. Under the required higher-severity rule, this supports high integrity impact.\nA:H - Even without full code execution, the kernel stack overflow can trigger an oops, panic, or other fatal corruption. The crafted packet can be sent remotely and repeatedly against a vulnerable tunnel endpoint."

Title
scsi: target: tcm_loop: Drain commands in target_reset handler
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: tcm_loop: Drain commands in target_reset handler
tcm_loop_target_reset() violates the SCSI EH contract: it returns SUCCESS
without draining any in-flight commands. The SCSI EH documentation
(scsi_eh.rst) requires that when a reset handler returns SUCCESS the driver
has made lower layers "forget about timed out scmds" and is ready for new
commands. Every other SCSI LLD (virtio_scsi, mpt3sas, ipr, scsi_debug,
mpi3mr) enforces this by draining or completing outstanding commands before
returning SUCCESS.
Because tcm_loop_target_reset() doesn't drain, the SCSI EH reuses in-flight
scsi_cmnd structures for recovery commands (e.g. TUR) while the target core
still has async completion work queued for the old se_cmd. The memset in
queuecommand zeroes se_lun and lun_ref_active, causing
transport_lun_remove_cmd() to skip its percpu_ref_put(). The leaked LUN
reference prevents transport_clear_lun_ref() from completing, hanging
configfs LUN unlink forever in D-state:
INFO: task rm:264 blocked for more than 122 seconds.
rm D 0 264 258 0x00004000
Call Trace:
__schedule+0x3d0/0x8e0
schedule+0x36/0xf0

configfs_unlink+0x156/0x1f0 [configfs]
vfs_unlink+0x109/0x290
do_unlinkat+0x1d5/0x2d0
Fix this by making tcm_loop_target_reset() actually drain commands:
1. Issue TMR_LUN_RESET via tcm_loop_issue_tmr() to drain all commands that
the target core knows about (those not yet CMD_T_COMPLETE).
2. Use blk_mq_tagset_busy_iter() to iterate all started requests and
flush_work() on each se_cmd — this drains any deferred completion work
for commands that already had CMD_T_COMPLETE set before the TMR (which
the TMR skips via __target_check_io_state()). This is the same pattern
used by mpi3mr, scsi_debug, and libsas to drain outstanding commands
during reset.

Title
fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath
When cifs_sanitize_prepath is called with an empty string or a string
containing only delimiters (e.g., "/"), the current logic attempts to
check *(cursor2 - 1) before cursor2 has advanced. This results in an
out-of-bounds read.
This patch adds an early exit check after stripping prepended
delimiters. If no path content remains, the function returns NULL.
The bug was identified via manual audit and verified using a
standalone test case compiled with AddressSanitizer, which
triggered a SEGV on affected inputs.

The triggering data is delivered over the network via SMB responses.\nAC:L - The trigger is a deterministic empty or delimiter-only prepath condition; no race or hard-to-control environmental condition is required. A malicious server or local mount caller can craft the relevant path form directly.\nPR:N - In the network scenario, the attacker only needs to operate the SMB/DFS endpoint that the victim client contacts and needs no privileges on the victim system. Local user-namespace reachability also exists before the final non-`FS_USERNS_MOUNT` mount denial, but the no-privilege malicious-server scenario is more severe.\nUI:R - The victim must initiate or otherwise cause an SMB/CIFS mount or DFS traversal to the attacker-controlled server. After that action, no further interaction is needed.\nS:U - The bug corrupts or reads kernel memory within the same host kernel security authority. It does not cross a separate scope such as a hypervisor, guest boundary, or IOMMU boundary.\nC:H - The immediate invalid access is a bounded read, but the same edge case can enter a path that treats memory before the prepath as part of the buffer, making this defensibly kernel memory corruption. Under the required overestimation rule, potential exploitation of kernel memory corruption is scored as high confidentiality impact.\nI:H - After the out-of-bounds read, if the preceding byte is a delimiter the old code decrements the cursor and writes a NUL before the prepath buffer. That conditional out-of-bounds write is kernel memory corruption and is scored as high integrity impact.\nA:H - The fix commit reports an AddressSanitizer SEGV on affected inputs, and the kernel path can produce invalid memory access or heap corruption. A repeatable kernel oops/panic or destabilization is therefore a high availability impact."

Title
ALSA: mixer: oss: Add card disconnect checkpoints
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: mixer: oss: Add card disconnect checkpoints
ALSA OSS mixer layer calls the kcontrol ops rather individually, and
pending calls might be not always caught at disconnecting the device.
For avoiding the potential UAF scenarios, add sanity checks of the
card disconnection at each entry point of OSS mixer accesses. The
rwsem is taken just before that check, hence the rest context should
be covered by that properly.
Severity
7.8 (High)

Title
netfilter: xt_tcpmss: check remaining length before reading optlen
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_tcpmss: check remaining length before reading optlen
Quoting reporter:
In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads
op[i+1] directly without validating the remaining option length.
If the last byte of the option field is not EOL/NOP (0/1), the code attempts
to index op[i+1]. In the case where i + 1 == optlen, this causes an
out-of-bounds read, accessing memory past the optlen boundary
(either reading beyond the stack buffer _opt or the
following payload).
Severity
8.2 (High)

There is no VM escape, IOMMU/DMA boundary crossing, or other scope-changing boundary involved.\nC:L - The bug is a bounded one-byte out-of-bounds read beyond the TCP options buffer, potentially into adjacent stack or skb data. Because it is only a single byte and is not a broad arbitrary read primitive, confidentiality impact is Low rather than High.\nI:N - The vulnerable operation only reads op[i+1] and uses it to advance the parser; it does not write to kernel memory or packet data. I found no control-flow or data-integrity primitive from this one-byte read.\nA:H - Malformed packets can repeatedly trigger the out-of-bounds read in softirq/netfilter packet processing. On instrumented or hardened kernels this can produce a KASAN/oops/panic, so availability impact is High under highest-defensible scoring."

Title
drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
The kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8
bytes via memset without checking the buffer size parameter. This allows
unprivileged userspace to trigger an out-of bounds kernel memory write
by passing a small buffer, leading to potential privilege
escalation.
Severity
7.8 (High)

There is no network, adjacent, or physical packet/device-input path.\nAC:L - The attacker controls the supplied event-page handle and can allocate a buffer smaller than `KFD_SIGNAL_EVENT_LIMIT * 8`, making the fixed-size `memset` out-of-bounds deterministic. No race or external condition is required.\nPR:L - The path is available to unprivileged userspace with access to KFD/AMDGPU device nodes, and the relevant ioctls have no capability flag or `capable()` gate. This is low privilege, not real administrator privilege.\nUI:N - Once a local attacker can execute code and open the device, exploitation only requires issuing ioctls. No victim user action is needed.\nS:U - The corruption occurs inside the kernel driver and impacts the same kernel security authority. This is standard local kernel compromise/DoS, not a cross-scope escape such as guest-to-host or IOMMU boundary bypass.\nC:H - The bug is an out-of-bounds kernel write into memory adjacent to a kernel-mapped GPU buffer, and kernel memory corruption can reasonably be leveraged to disclose sensitive kernel memory. Following the higher-severity rule for memory corruption, confidentiality impact is High.\nI:H - The vulnerable `memset` writes attacker-triggered data beyond the allocated object, giving a kernel memory corruption primitive. Out-of-bounds writes are scored as High integrity impact because they can plausibly be developed into privilege escalation or control-flow/data corruption.\nA:H - The out-of-bounds kernel write can corrupt adjacent kernel memory and readily crash or destabilize the kernel even without full exploitation. Kernel oops, panic, or persistent GPU/kernel failure is a High availability impact."
