CVE-2025-21867 (GCVE-0-2025-21867)

Title
bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type()
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type()
KMSAN reported a use-after-free issue in eth_skb_pkt_type()[1]. The
cause of the issue was that eth_skb_pkt_type() accessed skb's data
that didn't contain an Ethernet header. This occurs when
bpf_prog_test_run_xdp() passes an invalid value as the user_data
argument to bpf_test_init().
Fix this by returning an error when user_data is less than ETH_HLEN in
bpf_test_init(). Additionally, remove the check for "if (user_size >
size)" as it is unnecessary.

Additionally, remove the check for \"if (user_size \u003e\nsize)\" as it is unnecessary.\n\n[1]\nBUG: KMSAN: use-after-free in eth_skb_pkt_type include/linux/etherdevice.h:627 [inline]\nBUG: KMSAN: use-after-free in eth_type_trans+0x4ee/0x980 net/ethernet/eth.c:165\n eth_skb_pkt_type include/linux/etherdevice.h:627 [inline]\n eth_type_trans+0x4ee/0x980 net/ethernet/eth.c:165\n __xdp_build_skb_from_frame+0x5a8/0xa50 net/core/xdp.c:635\n xdp_recv_frames net/bpf/test_run.c:272 [inline]\n xdp_test_run_batch net/bpf/test_run.c:361 [inline]\n bpf_test_run_xdp_live+0x2954/0x3330 net/bpf/test_run.c:390\n bpf_prog_test_run_xdp+0x148e/0x1b10 net/bpf/test_run.c:1318\n bpf_prog_test_run+0x5b7/0xa30 kernel/bpf/syscall.c:4371\n __sys_bpf+0x6a6/0xe20 kernel/bpf/syscall.c:5777\n __do_sys_bpf kernel/bpf/syscall.c:5866 [inline]\n __se_sys_bpf kernel/bpf/syscall.c:5864 [inline]\n __x64_sys_bpf+0xa4/0xf0 kernel/bpf/syscall.c:5864\n x64_sys_call+0x2ea0/0x3d90 arch/x86/include/generated/asm/syscalls_64.h:322\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xd9/0x1d0 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\n\nUninit was created at:\n free_pages_prepare mm/page_alloc.c:1056 [inline]\n free_unref_page+0x156/0x1320 mm/page_alloc.c:2657\n __free_pages+0xa3/0x1b0 mm/page_alloc.c:4838\n bpf_ringbuf_free kernel/bpf/ringbuf.c:226 [inline]\n ringbuf_map_free+0xff/0x1e0 kernel/bpf/ringbuf.c:235\n bpf_map_free kernel/bpf/syscall.c:838 [inline]\n bpf_map_free_deferred+0x17c/0x310 kernel/bpf/syscall.c:862\n process_one_work kernel/workqueue.c:3229 [inline]\n process_scheduled_works+0xa2b/0x1b60 kernel/workqueue.c:3310\n worker_thread+0xedf/0x1550 kernel/workqueue.c:3391\n kthread+0x535/0x6b0 kernel/kthread.c:389\n ret_from_fork+0x6e/0x90 arch/x86/kernel/process.c:147\n ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244\n\nCPU: 1 UID: 0 PID: 17276 Comm: syz.1.16450 Not tainted 6.12.0-05490-g9bb88c659673 #8\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014"

on kernel built with MAX_SKB_FRAGS=45, where SKB_WITH_OVERHEAD(1024)
is smaller than GRO_MAX_HEAD.
Such built additionally contains the revert of the single page frag cache
so that napi_get_frags() ends up using the page frag allocator, triggering
the splat.
Note that the underlying issue is independent from the mentioned
revert; address it ensuring that the small head cache will fit either TCP
and GRO allocation and updating napi_alloc_skb() and __netdev_alloc_skb()
to select kmalloc() usage for any allocation fitting such cache.
Severity
No CVSS data available.

Commit c28c15b6d28a ("powerpc/code-patching: Use temporary mm for
Radix MMU") is inspired from x86 but unlike x86 is doesn't disable
KASAN reports during patching. This wasn't a problem at the begining
because __patch_mem() is not instrumented.
Commit 465cabc97b42 ("powerpc/code-patching: introduce
patch_instructions()") use copy_to_kernel_nofault() to copy several
instructions at once. But when using temporary mm the destination is
not regular kernel memory but a kind of kernel-like memory located
in user address space.

Title
ASoC: SOF: ipc4-topology: Harden loops for looking up ALH copiers
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Harden loops for looking up ALH copiers
Other, non DAI copier widgets could have the same stream name (sname) as
the ALH copier and in that case the copier->data is NULL, no alh_data is
attached, which could lead to NULL pointer dereference.
We could check for this NULL pointer in sof_ipc4_prepare_copier_module()
and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai()
will miscalculate the ALH device count, causing broken audio.
The correct fix is to harden the matching logic by making sure that the
1. widget is a DAI widget - so dai = w->private is valid
2. the dai (and thus the copier) is ALH copier

Title
tee: optee: Fix supplicant wait loop
Summary
In the Linux kernel, the following vulnerability has been resolved:
tee: optee: Fix supplicant wait loop
OP-TEE supplicant is a user-space daemon and it's possible for it
be hung or crashed or killed in the middle of processing an OP-TEE
RPC call. It becomes more complicated when there is incorrect shutdown
ordering of the supplicant process vs the OP-TEE client application which
can eventually lead to system hang-up waiting for the closure of the
client application.
Allow the client process waiting in kernel for supplicant response to
be killed rather than indefinitely waiting in an unkillable state. Also,
a normal uninterruptible wait should not have resulted in the hung-task
watchdog getting triggered, but the endless loop would.
This fixes issues observed during system reboot/shutdown when supplicant
got hung for some reason or gets crashed/killed which lead to client
getting hung in an unkillable state. It in turn lead to system being in
hung up state requiring hard power off/on to recover.
Severity
No CVSS data available.

Title
net_sched: hfsc: Fix a UAF vulnerability in class handling
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.

Title
ksmbd: prevent out-of-bounds stream writes by validating *pos
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: prevent out-of-bounds stream writes by validating *pos
ksmbd_vfs_stream_write() did not validate whether the write offset
(*pos) was within the bounds of the existing stream data length (v_len).
If *pos was greater than or equal to v_len, this could lead to an
out-of-bounds memory write.
This patch adds a check to ensure *pos is less than v_len before
proceeding. If the condition fails, -EINVAL is returned.

Title
xenbus: Use kref to track req lifetime
Summary
In the Linux kernel, the following vulnerability has been resolved:
xenbus: Use kref to track req lifetime
Marek reported seeing a NULL pointer fault in the xenbus_thread
callstack:
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: e030:__wake_up_common+0x4c/0x180
Call Trace:
<TASK>
__wake_up_common_lock+0x82/0xd0
process_msg+0x18e/0x2f0
xenbus_thread+0x165/0x1c0
process_msg+0x18e is req->cb(req). req->cb is set to xs_wake_up(), a
thin wrapper around wake_up(), or xenbus_dev_queue_reply(). It seems
like it was xs_wake_up() in this case.
It seems like req may have woken up the xs_wait_for_reply(), which
kfree()ed the req. When xenbus_thread resumes, it faults on the zero-ed
data.
Linux Device Drivers 2nd edition states:
"Normally, a wake_up call can cause an immediate reschedule to happen,
meaning that other processes might run before wake_up returns."
... which would match the behaviour observed.
Change to keeping two krefs on each request. One for the caller, and
one for xenbus_thread. Each will kref_put() when finished, and the last
will free it.
This use of kref matches the description in
Documentation/core-api/kref.rst
Severity
No CVSS data available.
