Title
afs: Fix potential null pointer dereference in afs_put_server
Summary
In the Linux kernel, the following vulnerability has been resolved:
afs: Fix potential null pointer dereference in afs_put_server
afs_put_server() accessed server->debug_id before the NULL check, which
could lead to a null pointer dereference. Move the debug_id assignment,
ensuring we never dereference a NULL server pointer.
Severity
No CVSS data available.

drm/gma500: Fix null dereference in hdmi teardown
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: Fix null dereference in hdmi teardown
pci_set_drvdata sets the value of pdev->driver_data to NULL,
after which the driver_data obtained from the same dev is
dereferenced in oaktrail_hdmi_i2c_exit, and the i2c_dev is
extracted from it. To prevent this, swap these calls.
Found by Linux Verification Center (linuxtesting.org) with Svacer.

Title
ipvs: Defer ip_vs_ftp unregister during netns cleanup
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: Defer ip_vs_ftp unregister during netns cleanup
On the netns cleanup path, __ip_vs_ftp_exit() may unregister ip_vs_ftp
before connections with valid cp->app pointers are flushed, leading to a
use-after-free.
Fix this by introducing a global `exiting_module` flag, set to true in
ip_vs_ftp_exit() before unregistering the pernet subsystem. In
__ip_vs_ftp_exit(), skip ip_vs_ftp unregister if called during netns
cleanup (when exiting_module is false) and defer it to
__ip_vs_cleanup_batch(), which unregisters all apps after all connections
are flushed. If called during module exit, unregister ip_vs_ftp
immediately.

Title
tracing: dynevent: Add a missing lockdown check on dynevent
Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: dynevent: Add a missing lockdown check on dynevent
Since dynamic_events interface on tracefs is compatible with
kprobe_events and uprobe_events, it should also check the lockdown
status and reject if it is set.
Severity
No CVSS data available.

Title
crypto: af_alg - Fix incorrect boolean values in af_alg_ctx
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Fix incorrect boolean values in af_alg_ctx
Commit 1b34cbbf4f01 ("crypto: af_alg - Disallow concurrent writes in
af_alg_sendmsg") changed some fields from bool to 1-bit bitfields of
type u32.
However, some assignments to these fields, specifically 'more' and
'merge', assign values greater than 1. These relied on C's implicit
conversion to bool, such that zero becomes false and nonzero becomes
true.
With a 1-bit bitfields of type u32 instead, mod 2 of the value is taken
instead, resulting in 0 being assigned in some cases when 1 was intended.
Fix this by restoring the bool type.
Severity
No CVSS data available.

Title
KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O
When completing emulation of instruction that generated a userspace exit
for I/O, don't recheck L1 intercepts as KVM has already finished that
phase of instruction execution, i.e. has already committed to allowing L2
to perform I/O. If L1 (or host userspace) modifies the I/O permission
bitmaps during the exit to userspace, KVM will treat the access as being
intercepted despite already having emulated the I/O access.
Pivot on EMULTYPE_NO_DECODE to detect that KVM is completing emulation.
Of the three users of EMULTYPE_NO_DECODE, only complete_emulated_io() (the
intended "recipient") can reach the code in question. gp_interception()'s
use is mutually exclusive with is_guest_mode(), and
complete_emulated_insn_gp() unconditionally pairs EMULTYPE_NO_DECODE with
EMULTYPE_SKIP.
The bad behavior was detected by a syzkaller program that toggles port I/O
interception during the userspace I/O exit, ultimately resulting in a WARN
on vcpu->arch.pio.count being non-zero due to KVM no completing emulation
of the I/O instruction.

This happens because of a race condition between:
- The 9p client sending an invalid flush request and later cleaning it up;
- The 9p client in p9_read_work() canceled all pending requests.

Commit 74d6a5d56629 ("9p/trans_fd: Fix concurrency del of req_list in
p9_fd_cancelled/p9_read_work") fixes a concurrency issue in the 9p filesystem
client where the req_list could be deleted simultaneously by both
p9_read_work and p9_fd_cancelled functions, but for the case where req->status
equals REQ_STATUS_RCVD.
Update the check for req->status in p9_fd_cancelled to skip processing not
just received requests, but anything that is not SENT, as whatever
changed the state from SENT also removed the request from its list.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
[updated the check from status == RECV || status == ERROR to status != SENT]

"value": "AV:L - The vulnerable path is entered only from `p9_client_flush()`, which runs solely when a local process\u0027s 9p RPC returns `-ERESTARTSYS` from `io_wait_event_killable()` \u2014 i.e. it requires a local task doing filesystem I/O on a 9p mount and receiving a signal. A remote 9p server can trigger `p9_conn_cancel()` but cannot supply the signal half of the race, so no purely network-based trigger exists.\nAC:L - The attacker drives both sides of the race with their own threads: signals to force the `-ERESTARTSYS`/`p9_client_flush()` path, and late replies for already-flushed tags (or, with `trans=fd`, direct writes/hangups on the attacker-owned pipe or socketpair) to force `p9_conn_cancel()` into the window. The window is repeatable at will across many threads and was reached by syzkaller with no special preconditions.\nPR:L - On the common deployments where a 9p mount already exists (QEMU/KVM virtfs shares, WSL2 9p-over-hvsock with `trans=fd`, Crostini, kata containers, 9p network roots), any unprivileged local account with access to the mount can issue RPCs, self-signal to reach `p9_fd_cancelled()`, and provoke `p9_conn_cancel()` \u2014 no capability is checked anywhere on this path.\nUI:N - The attacking process performs every step itself \u2014 open/read on the 9p mount, deliver the fatal signal, and induce the transport error. The pre-existing mount is system configuration, not a victim action taken during the attack.\nS:U - The corruption is confined to the kernel\u0027s own slab (`p9_req_cache` and the fcall buffers) within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The extra `p9_req_put()` frees the `struct p9_req_t` and its `tc`/`rc` buffers while `p9_client_rpc()` still uses them, so `p9_check_errors()` parses a reallocated heap object as a 9p reply \u2014 an attacker who sprays the freed chunk obtains a controlled read of kernel heap contents (pointers, keys, KASLR data).\nI:H - The same premature free yields a double free of a slab object plus a `list_del()` on `req-\u003ereq_list` after the object may be reclaimed, giving an attacker-controlled `next-\u003eprev = prev` write primitive over kernel memory, which is the classic path to control-flow hijack and privilege escalation.\nA:H - Even unweaponized the bug reliably panics the kernel \u2014 the reported syzkaller crash is a general protection fault in `__list_del()` on `LIST_POISON` at `0xdead000000000108`, and the refcount underflow/double free corrupts the SLUB freelist; the attacker can repeat it at will."
