Title
gpio: sch: use raw_spinlock_t in the irq startup path
Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: sch: use raw_spinlock_t in the irq startup path
sch_irq_unmask() enables the GPIO IRQ and then updates the controller
state through sch_irq_mask_unmask(), which takes sch->lock with
spin_lock_irqsave(). The callback can be reached from irq_startup()
while setting up a requested IRQ. That path is not sleepable, but on
PREEMPT_RT a regular spinlock_t becomes a sleeping lock.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the request_threaded_irq() -> __setup_irq() ->
irq_startup() -> sch_irq_unmask() -> sch_irq_mask_unmask() carrier and
used the original spin_lock_irqsave(&sch->lock) edge. Lockdep reported:
BUG: sleeping function called from invalid context
hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]
sch_rt_spin_lock_irqsave+0x1c/0x30 [vuln_msv]
sch_irq_mask_unmask.constprop.0+0x31/0x70 [vuln_msv]
__setup_irq.constprop.0+0xd/0x30 [vuln_msv]
Convert the SCH controller lock to raw_spinlock_t. The same lock is
also used by the GPIO direction and value callbacks, but those critical
sections only update MMIO-backed GPIO registers and do not contain
sleepable operations. Keeping this register lock non-sleeping is
therefore appropriate for the irqchip callbacks and does not change the
GPIO-side locking contract.

Title
gpio: eic-sprd: use raw_spinlock_t in the irq startup path
Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: eic-sprd: use raw_spinlock_t in the irq startup path
sprd_eic_irq_unmask() enables the GPIO IRQ and then updates controller
state through sprd_eic_update(), which takes sprd_eic->lock with
spin_lock_irqsave(). The callback can be reached from irq_startup()
while setting up a requested IRQ. That path is not sleepable, but on
PREEMPT_RT a regular spinlock_t becomes a sleeping lock.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the request_threaded_irq() -> __setup_irq() ->
irq_startup() -> sprd_eic_irq_unmask() -> sprd_eic_update() carrier and
used the original spin_lock_irqsave(&sprd_eic->lock) edge. Lockdep
BUG: sleeping function called from invalid context
hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]

Convert the Spreadtrum EIC controller lock to raw_spinlock_t. The
locked section only serializes MMIO register updates and does not contain
sleepable operations, so keeping it non-sleeping is appropriate for the
irqchip callbacks.

Title
NTB: epf: Avoid calling pci_irq_vector() from hardirq context
Summary
In the Linux kernel, the following vulnerability has been resolved:
NTB: epf: Avoid calling pci_irq_vector() from hardirq context
ntb_epf_vec_isr() calls pci_irq_vector() in hardirq context to derive
the vector number. pci_irq_vector() calls msi_get_virq() that takes a
mutex and can therefore trigger "scheduling while atomic" splats:
BUG: scheduling while atomic: kworker/u33:0/55/0x00010001
...
Call trace:
...
schedule+0x38/0x110
schedule_preempt_disabled+0x28/0x50
__mutex_lock.constprop.0+0x848/0x908
__mutex_lock_slowpath+0x18/0x30
mutex_lock+0x4c/0x60
msi_domain_get_virq+0xe8/0x138

__handle_irq_event_percpu+0x70/0x3a8
handle_irq_event+0x48/0x100
handle_edge_irq+0x100/0x1c8
...
Cache the Linux IRQ number for vector 0 when vectors are allocated and
use it as a base in the ISR. Running the ISR in a threaded IRQ handler
would also avoid the problem, but that would be unnecessary here.

fs/ntfs3: validate Dirty Page Table capacity in log_replay copy_lcns
In the analysis pass of $LogFile journal replay, log_replay() copies
LCNs from each action log record into an existing Dirty Page Table
(DPT) entry without bounding the destination index. A crafted NTFS
image with DPT entry lcns_follow=1 and an action log record with
lcns_follow=2 produces a kernel slab out-of-bounds write at mount
time:
BUG: KASAN: slab-out-of-bounds in log_replay+0x654c/0xdb60
Write of size 8 at addr ffff8880095e1040 by task mount
Two attacker-controlled fields can drive j+i past the allocated
page_lcns[] array:
1. dp->lcns_follow (capacity) can be smaller than lrh->lcns_follow.
2. lrh->target_vcn may be smaller than dp->vcn, making the u64
subtraction wrap to a huge size_t.
Validate target VCN delta and per-record LCN count against the
DPT entry capacity, bail via the existing out: cleanup label with
-EINVAL.
This mirrors the bounds-check pattern added in commit b2bc7c44ed17
("fs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot")
and commit 0ca0485e4b2e ("fs/ntfs3: validate rec->used in
journal-replay file record check").

Title
Bluetooth: MGMT: Fix UAF of hci_conn_params in add_device_complete
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: Fix UAF of hci_conn_params in add_device_complete
add_device_complete() runs from the hci_cmd_sync_work kworker, which
holds only hci_req_sync_lock and *not* hci_dev_lock. It calls
hci_conn_params_lookup() and then dereferences the returned object
(params->flags) without taking hci_dev_lock:
params = hci_conn_params_lookup(hdev, &cp->addr.bdaddr,
le_addr_type(cp->addr.type));
...
device_flags_changed(NULL, hdev, &cp->addr.bdaddr,
cp->addr.type, hdev->conn_flags,
params ? params->flags : 0);
hci_conn_params_lookup() walks hdev->le_conn_params and is documented to
require hdev->lock. A concurrent MGMT_OP_REMOVE_DEVICE
(remove_device()), which does run under hci_dev_lock, can call
hci_conn_params_free() to list_del() and kfree() the very object the
lookup returned, so the subsequent params->flags read touches freed
memory [0].
Hold hci_dev_lock() across the hci_conn_params_lookup() and the read of
params->flags (and the matching event emission) so the lookup result
cannot be freed by a concurrent remove_device() before it is used,
honouring the locking contract of hci_conn_params_lookup().
[0]: (trailing page/memory-state dump trimmed)

Bluetooth: L2CAP: Fix UAF in channel timeout by holding conn ref
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix UAF in channel timeout by holding conn ref
l2cap_chan_timeout() runs asynchronously and accesses chan->conn. If
the connection is torn down while the timer is running or pending,
chan->conn can be freed, leading to a use-after-free when the timer
worker attempts to lock conn->lock:

Fix it by having chan->conn hold a reference to l2cap_conn (via
l2cap_conn_get) when the channel is added to the connection, and
releasing it in the channel destructor. This ensures the l2cap_conn
remains alive as long as the channel exists.
A new FLAG_DEL channel flag is introduced to indicate that the ch

Title
audit: Fix data races of skb_queue_len() readers on audit_queue
Summary
In the Linux kernel, the following vulnerability has been resolved:
audit: Fix data races of skb_queue_len() readers on audit_queue
Multiple readers access audit_queue.qlen via skb_queue_len() without
holding the queue lock or using READ_ONCE(), while kauditd writes to
this field via the skb_dequeue() → __skb_unlink() path with WRITE_ONCE()
protected by a spinlock. This constitutes data races.
All affected skb_queue_len(&audit_queue) call sites:
- kauditd_thread() wait_event_freezable() condition
- audit_receive_msg() AUDIT_GET handler (s.backlog assignment)
- audit_receive() backlog check
- audit_log_start() backlog check and pr_warn()
KCSAN reports the following conflicting access pattern (one example):
==================================================================
BUG: KCSAN: data-race in audit_log_start / skb_dequeue
write (marked) to 0xffffffff8512ee20 of 4 bytes by task 661 on cpu 57:

entry_SYSCALL_64_after_hwframe+0x76/0xe0
value changed: 0x00000001 -> 0x00000000
==================================================================
Resolve the race by switching to lockless helper skb_queue_len_lockless(),
which internally uses READ_ONCE() and properly pairs with the WRITE_ONCE()
write accesses already present on the writer side.

Title
net: af_key: initialize alg_key_len for IPComp states
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: af_key: initialize alg_key_len for IPComp states
pfkey_msg2xfrm_state() handles the IPComp (SADB_X_SATYPE_IPCOMP) case by
allocating x->calg and copying only the algorithm name:
x->calg = kmalloc_obj(*x->calg);
if (!x->calg) {
err = -ENOMEM;
goto out;
}
strcpy(x->calg->alg_name, a->name);
x->props.calgo = sa->sadb_sa_encrypt;
Unlike the authentication (x->aalg) and encryption (x->ealg) branches of
the same function, the compression branch never initializes
calg->alg_key_len. IPComp carries no key and the allocation only
reserves sizeof(struct xfrm_algo) (i.e. no room for a key), so the field
is left containing uninitialized slab data.
calg->alg_key_len is later used as a length by xfrm_algo_clone() when an
IPComp state is cloned during XFRM_MSG_MIGRATE:
xfrm_state_migrate()
xfrm_state_clone_and_setup()
x->calg = xfrm_algo_clone(orig->calg);
kmemdup(orig, xfrm_alg_len(orig));
where xfrm_alg_len() returns sizeof(*alg) + (alg_key_len + 7) / 8. With
a non-zero garbage alg_key_len, kmemdup() reads past the end of the
68-byte calg object. Adding an IPComp SA via PF_KEY and then migrating
it triggers (net-next, KASAN, init_on_alloc=0):
BUG: KASAN: slab-out-of-bounds in kmemdup_noprof+0x44/0x60

The buggy address belongs to the object at ff11000025a74980
which belongs to the cache kmalloc-96 of size 96
The buggy address is located 0 bytes inside of
allocated 68-byte region [ff11000025a74980, ff11000025a749c4)
Depending on the uninitialized value the same field can instead request
an oversized kmemdup() allocation and make the migration clone fail.
The XFRM netlink path is not affected: verify_one_alg() rejects an
XFRMA_ALG_COMP attribute shorter than xfrm_alg_len(), so a calg added via
XFRM_MSG_NEWSA is always self-consistent.
Initialize calg->alg_key_len to 0, matching the aalg/ealg branches.

Title
ksmbd: fix use-after-free of a deferred file_lock on SMB2_CLOSE then SMB2_CANCEL
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free of a deferred file_lock on SMB2_CLOSE then SMB2_CANCEL
Commit f580d27e8928 ("ksmbd: fix use-after-free of a deferred file_lock on
double SMB2_CANCEL") made smb2_cancel() skip a work whose state is
KSMBD_WORK_CANCELLED, so its cancel_fn cannot be fired a second time. But
KSMBD_WORK has three states (ACTIVE, CANCELLED, CLOSED), and the same
freeing producer path is reached for CLOSED too:
SMB2_CLOSE on the locking handle -> set_close_state_blocked_works() sets
the deferred work's state to KSMBD_WORK_CLOSED and wakes the smb2_lock()
worker. The worker takes the non-ACTIVE early-exit, locks_free_lock()s
the file_lock and, because the state is not KSMBD_WORK_CANCELLED, takes
the STATUS_RANGE_NOT_LOCKED branch with "goto out2" -- which, like the
cancelled branch, skips release_async_work(). The work stays on
conn->async_requests with a live cancel_fn = smb2_remove_blocked_lock
pointing at the freed file_lock.
A subsequent SMB2_CANCEL for the same AsyncId then passes the
KSMBD_WORK_CANCELLED-only guard (its state is KSMBD_WORK_CLOSED), so
smb2_cancel() fires cancel_fn again over the freed file_lock -- the same
use-after-free fixed, via SMB2_CLOSE instead of a first SMB2_CANCEL:
BUG: KASAN: slab-use-after-free in __locks_delete_block
__locks_delete_block
locks_delete_block
ksmbd_vfs_posix_lock_unblock
smb2_remove_blocked_lock
smb2_cancel <- 2nd SMB2_CANCEL fires cancel_fn
handle_ksmbd_work
Allocated by ...: locks_alloc_lock <- smb2_lock
Freed by ...: locks_free_lock <- smb2_lock (non-ACTIVE early-exit)
... cache file_lock_cache of size 192
Reproduced on mainline 7.1-rc7 (which already contains f580d27e8928) with
KASAN by an authenticated SMB client; the double-SMB2_CANCEL control is
silent on that kernel, so the splat is attributable to the CLOSE trigger.
Only an ACTIVE deferred work may have its cancel_fn fired: both terminal
states (CANCELLED and CLOSED) reach the smb2_lock() early-exit that frees
the file_lock and skips release_async_work(). Guard on KSMBD_WORK_ACTIVE
so any non-active work is skipped.

Title
crypto: qat - fix VF2PF work teardown race in adf_disable_sriov()
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix VF2PF work teardown race in adf_disable_sriov()
The VF2PF interrupt handler queues PF-side response work that stores a
raw pointer to per-VF state (struct adf_accel_vf_info). Currently,
adf_disable_sriov() destroys per-VF mutexes and frees vf_info without
stopping new VF2PF work or waiting for in-flight workers to complete. A
concurrently scheduled or already queued worker can then dereference
freed memory.
This manifests as a use-after-free when KASAN is enabled:
BUG: KASAN: null-ptr-deref in mutex_lock+0x76/0xe0
Write of size 8 at addr 0000000000000260 by task kworker/24:2/...
Workqueue: qat_pf2vf_resp_wq adf_iov_send_resp [intel_qat]
Call Trace:

adf_gen4_pfvf_send+0xd4/0x1f0 [intel_qat]

worker_thread+0x4dd/0xd30
kthread+0x326/0x410
ret_from_fork+0x33b/0x670
Add a PF-local flag, vf2pf_disabled, that gates work queueing, worker
processing, and interrupt re-enabling during teardown. Set this flag
atomically with the hardware interrupt mask inside
adf_disable_all_vf2pf_interrupts(). After masking, synchronize the AE
cluster MSI-X interrupt and flush the PF response workqueue before
tearing down per-VF locks and state so all in-flight work completes
before vf_info is destroyed.
Introduce adf_enable_all_vf2pf_interrupts() to clear the flag and
unmask all VF2PF interrupts under the same lock when SR-IOV is
re-enabled. This ensures the software flag and hardware state transition
atomically on both the enable and disable paths.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: qat - fix VF2PF work teardown race in adf_disable_sriov()\n\nThe VF2PF interrupt handler queues PF-side response work that stores a\nraw pointer to per-VF state (struct adf_accel_vf_info). Currently,\nadf_disable_sriov() destroys per-VF mutexes and frees vf_info without\nstopping new VF2PF work or waiting for in-flight workers to complete. A\nconcurrently scheduled or already queued worker can then dereference\nfreed memory.\n\nThis manifests as a use-after-free when KASAN is enabled:\n\n BUG: KASAN: null-ptr-deref in mutex_lock+0x76/0xe0\n Write of size 8 at addr 0000000000000260 by task kworker/24:2/...\n Workqueue: qat_pf2vf_resp_wq adf_iov_send_resp [intel_qat]\n Call Trace:\n kasan_report+0x119/0x140\n mutex_lock+0x76/0xe0\n adf_gen4_pfvf_send+0xd4/0x1f0 [intel_qat]\n adf_recv_and_handle_vf2pf_msg+0x290/0x360 [intel_qat]\n adf_iov_send_resp+0x8c/0xe0 [intel_qat]\n process_one_work+0x6ac/0xfd0\n worker_thread+0x4dd/0xd30\n kthread+0x326/0x410\n ret_from_fork+0x33b/0x670\n\nAdd a PF-local flag, vf2pf_disabled, that gates work queueing, worker\nprocessing, and interrupt re-enabling during teardown. Set this flag\natomically with the hardware interrupt mask inside\nadf_disable_all_vf2pf_interrupts(). After masking, synchronize the AE\ncluster MSI-X interrupt and flush the PF response workqueue before\ntearing down per-VF locks and state so all in-flight work completes\nbefore vf_info is destroyed.\n\nIntroduce adf_enable_all_vf2pf_interrupts() to clear the flag and\nunmask all VF2PF interrupts under the same lock when SR-IOV is\nre-enabled. This ensures the software flag and hardware state transition\natomically on both the enable and disable paths."

"value": "AV:L - Exploitation originates from a local process or guest with direct access to an assigned QAT VF, using VF MMIO or the VF driver to generate VF2PF messages; it is not network-reachable.\nAC:L - The VF controls mailbox generation, restart-complete signaling, and acknowledgement behavior, and can keep response work active for up to one second while teardown proceeds. VF removal itself also emits shutdown traffic, making the race repeatedly attacker-alignable.\nPR:L - The attacker needs authorized access to an assigned QAT VF, which can be delegated through VFIO to an unprivileged process or tenant VM. No host administrative capability is required during management-initiated teardown or reset.\nUI:N - Exploitation requires no victim-user action; device teardown, hot-unplug, shutdown, or automatic error recovery supplies the concurrent lifecycle event.\nS:C - In a virtualized deployment, a tenant controlling an assigned VF corrupts memory in the host PF kernel, crossing the guest-to-host isolation boundary.\nC:H - The freed VF-state allocation contains kernel pointers and synchronization state, and reclamation of the stale object can support disclosure of arbitrary host-kernel memory.\nI:H - The worker performs writes through destroyed mutexes and stale pointers into freed or reallocated memory, providing memory-corruption primitives potentially usable for host-kernel code execution.\nA:H - The observed use-after-free produces invalid kernel writes and NULL-pointer dereferences, allowing a kernel oops or panic and complete host availability loss."
