Title
Input: mtk-pmic-keys - fix possible null pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: mtk-pmic-keys - fix possible null pointer dereference
In mtk_pmic_keys_probe, the regs parameter is only set if the button is
parsed in the device tree. However, on hardware where the button is left
floating, that node will most likely be removed not to enable that
input. In that case the code will try to dereference a null pointer.
Let's use the regs struct instead as it is defined for all supported
platforms. Note that it is ok setting the key reg even if that latter is
disabled as the interrupt won't be enabled anyway.

Title
wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation
Currently during the multi-link element defragmentation process, the
multi-link element length added to the total IEs length when calculating
the length of remaining IEs after the multi-link element in
cfg80211_defrag_mle(). This could lead to out-of-bounds access if the
multi-link element or its corresponding fragment elements are the last
elements in the IEs buffer.
To address this issue, correctly calculate the remaining IEs length by
deducting the multi-link element end offset from total IEs end offset.
Severity
8.1 (High)

This is the standard WiFi frame-injection adjacency requirement, not a routable network path.\nAC:L - The attacker fully controls the frame contents and can deterministically place a valid Basic Multi-Link element as the final IE, which makes the fragment-scan loop dereference memory exactly at `ie + ielen` on its first iteration \u2014 no race, no memory-layout luck required for the overread itself. Probe responses are accepted whenever the STA scans (foreground or PNO/sched scan), and MAC randomization or simply answering an observed probe request satisfies the DA check in `ieee80211_scan_accept_presp()`.\nPR:N - Scan-result parsing happens before any authentication or association, so an unauthenticated attacker with no credentials, no key material, and no prior relationship to the victim can reach the code. The attacker needs no account on the target and no privileges of any kind.\nUI:N - Linux/Android stations run periodic background scans and scheduled scans (PNO) automatically via wpa_supplicant/NetworkManager without any user action, and every such scan feeds received probe responses into the vulnerable path. No victim click, mount, or connection attempt is needed.\nS:U - The out-of-bounds read and any resulting fault occur entirely within the kernel\u0027s own security authority on the affected host; no VM, IOMMU, container, or sandbox boundary is crossed.\nC:H - The loop reads up to `p + 2*mle-\u003edatalen` bytes (potentially ~2.5 KB for a maximum-length probe response with the MLE placed last) beyond the end of the receive buffer into adjacent kernel heap memory \u2014 far more than a strictly bounded few-byte overread. The out-of-bounds bytes are actively interpreted as element headers and steer loop continuation and the computed allocation size, so attacker-observable behaviour depends on kernel memory the attacker must not be able to read.\nI:N - The defect is confined to the length computation of a read-only scanning loop; the erroneous bound can only over-estimate `buf_len`, and the subsequent `cfg80211_defragment_element()` call still uses the correct `ielen` and rejects overflow with `-ENOSPC`, so no out-of-bounds write or corruption of kernel state occurs.\nA:H - The walk can run kilobytes past the receive buffer into unmapped or guarded memory \u2014 KFENCE (default-enabled on Android GKI and several distro kernels), KASAN, and DEBUG_PAGEALLOC turn this into an unhandled kernel page fault/oops. The attacker can retransmit the crafted probe response indefinitely with no authentication, so repeated triggering makes a kernel panic a practical denial of service."

Title
net_sched: Flush gso_skb list too during ->change()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: Flush gso_skb list too during ->change()
Previously, when reducing a qdisc's limit via the ->change() operation, only
the main skb queue was trimmed, potentially leaving packets in the gso_skb
list. This could result in NULL pointer dereference when we only check
sch->limit against sch->q.qlen.
This patch introduces a new helper, qdisc_dequeue_internal(), which ensures
both the gso_skb list and the main queue are properly flushed when trimming
excess packets. All relevant qdiscs (codel, fq, fq_codel, fq_pie, hhf, pie)
are updated to use this helper in their ->change() routines.
Severity
No CVSS data available.

can: m_can: m_can_class_allocate_dev(): initialize spin lock on device probe
Summary
In the Linux kernel, the following vulnerability has been resolved:
can: m_can: m_can_class_allocate_dev(): initialize spin lock on device probe
The spin lock tx_handling_spinlock in struct m_can_classdev is not
being initialized. This leads the following spinlock bad magic
complaint from the kernel, eg. when trying to send CAN frames with
cansend from can-utils:

Title
module: ensure that kobject_put() is safe for module type kobjects
Summary
In the Linux kernel, the following vulnerability has been resolved:
module: ensure that kobject_put() is safe for module type kobjects
In 'lookup_or_create_module_kobject()', an internal kobject is created
using 'module_ktype'. So call to 'kobject_put()' on error handling
path causes an attempt to use an uninitialized completion pointer in
'module_kobject_release()'. In this scenario, we just want to release
kobject without an extra synchronization required for a regular module
unloading process, so adding an extra check whether 'complete()' is
actually required makes 'kobject_put()' safe.
Severity
No CVSS data available.

Title
KVM: arm64: Fix uninitialized memcache pointer in user_mem_abort()
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix uninitialized memcache pointer in user_mem_abort()
Commit fce886a60207 ("KVM: arm64: Plumb the pKVM MMU in KVM") made the
initialization of the local memcache variable in user_mem_abort()
conditional, leaving a codepath where it is used uninitialized via
kvm_pgtable_stage2_map().
This can fail on any path that requires a stage-2 allocation
without transition via a permission fault or dirty logging.
Fix this by making sure that memcache is always valid.

Title
fs/erofs/fileio: call erofs_onlinefolio_split() after bio_add_folio()
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/erofs/fileio: call erofs_onlinefolio_split() after bio_add_folio()
If bio_add_folio() fails (because it is full),
erofs_fileio_scan_folio() needs to submit the I/O request via
erofs_fileio_rq_submit() and allocate a new I/O request with an empty
`struct bio`. Then it retries the bio_add_folio() call.
However, at this point, erofs_onlinefolio_split() has already been
called which increments `folio->private`; the retry will call
erofs_onlinefolio_split() again, but there will never be a matching
erofs_onlinefolio_end() call. This leaves the folio locked forever
and all waiters will be stuck in folio_wait_bit_common().
This bug has been added by commit ce63cb62d794 ("erofs: support
unencoded inodes for fileio"), but was practically unreachable because
there was room for 256 folios in the `struct bio` - until commit
9f74ae8c9ac9 ("erofs: shorten bvecs[] for file-backed mounts") which
reduced the array capacity to 16 folios.
It was now trivial to trigger the bug by manually invoking readahead
from userspace, e.g.:
posix_fadvise(fd, 0, st.st_size, POSIX_FADV_WILLNEED);
This should be fixed by invoking erofs_onlinefolio_split() only after
bio_add_folio() has succeeded. This is safe: asynchronous completions
invoking erofs_onlinefolio_end() will not unlock the folio because
erofs_fileio_scan_folio() is still holding a reference to be released
by erofs_onlinefolio_end() at the end.
Severity

io_uring/fdinfo: grab ctx->uring_lock around io_uring_show_fdinfo()
Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/fdinfo: grab ctx->uring_lock around io_uring_show_fdinfo()
Not everything requires locking in there, which is why the 'has_lock'
variable exists. But enough does that it's a bit unwieldy to manage.
Wrap the whole thing in a ->uring_lock trylock, and just return
with no output if we fail to grab it. The existing trylock() will
already have greatly diminished utility/output for the failure case.
This fixes an issue with reading the SQE fields, if the ring is being
actively resized at the same time.

{
"lang": "en",
"value": "AV:L - The vulnerable path is reached purely through local syscalls \u2014 `io_uring_setup()`/`io_uring_register(IORING_REGISTER_RESIZE_RINGS)` plus a `read()` of `/proc/self/fdinfo/\u003cring fd\u003e`. No remote or adjacent-network data is processed anywhere along the path.\nAC:L - The attacker controls both sides of the race, spinning one thread on resize and another on fdinfo reads, and can widen the window arbitrarily by using a large old ring and a small new ring so the unlocked SQE/CQE dump loop runs for thousands of iterations. No condition outside the attacker\u0027s influence is required.\nPR:L - Any unprivileged local user can create an io_uring instance with `IORING_SETUP_DEFER_TASKRUN|SINGLE_ISSUER` and resize it; no capability check exists on the register path. Reading one\u0027s own `/proc/self/fdinfo/\u003cfd\u003e` always satisfies the `ptrace_may_access(PTRACE_MODE_READ_FSCREDS)` gate in `proc_fdinfo_permission()`.\nUI:N - The entire attack runs inside the attacker\u0027s own process using its own ring fd and its own procfs entries. No other user or administrator has to do anything.\nS:U - The stale-pointer reads, faults, and information disclosure all occur in kernel context against the attacking process\u0027s own kernel objects, within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Stale `ctx-\u003erings`/`ctx-\u003esq_array` pointers are dereferenced after `release_pages()`/`vunmap()` frees the old ring regions, and stale `sq_entries`/`sq_mask` combined with the new smaller `ctx-\u003esq_sqes` yield an out-of-bounds read of up to ~2 MB past the SQE region at an offset the attacker chooses through the userspace-mapped `sq_array`. The recovered bytes (`opcode, fd, flags, off, addr, rw_flags, buf_index, user_data`, or a full 128 bytes with SQE128) are `seq_printf()`ed directly into the fdinfo output the attacker reads, giving a repeatable kernel-memory disclosure primitive.\nI:H - This is a use-after-free on freed ring pages that can be recycled into arbitrary kernel allocations and then heap-sprayed by the attacker to steer the derived out-of-bounds dereference, consistent with UAF scoring practice for this subsystem. The leaked heap contents and kernel pointers also defeat KASLR and directly enable control-flow-hijacking exploitation of adjacent kernel state.\nA:H - `ctx-\u003erings` and `ctx-\u003esq_sqes` are transiently NULL during the swap, so `READ_ONCE(r-\u003esq.head)` and `\u0026ctx-\u003esq_sqes[sq_idx \u003c\u003c sq_shift]` produce a NULL-pointer oops, and dereferencing a `vunmap()`\u0027d old region or reading megabytes past the new SQE region faults the kernel. An unprivileged user can trigger these in a tight loop for a reliable panic."
