UBUNTU-CVE-2025-38477

In the Linux kernel, the following vulnerability has been resolved: net/sched: schqfq: Fix race condition on qfqaggregate A race condition can occur when 'agg' is modified in qfqchangeagg called during qfqenqueue while other threads access it concurrently. For example, qfqdumpclass may trigger a...

kernel: net/sched: fix use-after-free in taprio_dev_notifier

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix use-after-free in tapriodevnotifier Since taprio’s tapriodevnotifier isn’t protected by an RCU read-side critical section, a race with advancesched can lead to a use-after-free. Adding rcureadlock inside...

kernel: rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()

A locking violation was found in the Linux kernel RCU-tasks subsystem's callback list initialization. During system boot, the initialization code calls prinfo while holding the rtp-cbsgbllock spinlock, causing a potentially sleeping function to be called in atomic context, which results in kernel...

UBUNTU-CVE-2025-38448

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: userial: Fix race condition in TTY wakeup A race condition occurs when gsstartio calls either gsstartrx or gsstarttx, as those functions briefly drop the portlock for usbepqueue. This allows gsclose and...

UBUNTU-CVE-2025-38459

In the Linux kernel, the following vulnerability has been resolved: atm: clip: Fix infinite recursive call of clippush. syzbot reported the splat below. 0 This happens if we call ioctlATMARPMKIP more than once. During the first call, clipmkip sets clippush to vcc-push, and the second call copies ...

CVE-2025-38464 tipc: Fix use-after-free in tipc_conn_close().

In the Linux kernel, the following vulnerability has been resolved: tipc: Fix use-after-free in tipcconnclose. syzbot reported a null-ptr-deref in tipcconnclose during netns dismantle. 0 tipctopsrvstop iterates tipcnetnet-topsrv-connidr and calls tipcconnclose for each tipcconn. The problem is th...

CVE-2025-38373

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix potential deadlock in MR deregistration The issue arises when kzalloc is invoked while holding umemmutex or any other lock acquired under umemmutex. This is problematic because kzalloc can trigger fsreclaimaqcuire,...

CVE-2025-38353

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix taking invalid lock on wedge If device wedges on e.g. GuC upload, the submission is not yet enabled and the state is not even initialized. Protect the wedge call so it does nothing in this case. It fixes the following...

UBUNTU-CVE-2025-38388

In the Linux kernel, the following vulnerability has been resolved: firmware: armffa: Replace mutex with rwlock to avoid sleep in atomic context The current use of a mutex to protect the notifier hashtable accesses can lead to issues in the atomic context. It results in the below kernel warnings:...

CVE-2025-38404

CVE-2025-38404 affects the Linux kernel USB Type-C/displayport subsystem. The issue is a potential deadlock caused by recursive locking of cros_typec_altmode_data::mutex when a mutex-protected path calls typec_altmode_exit() from within the same context. The documented fix defers the typec_altmod...

CVE-2025-38373

CVE-2025-38373 concerns the Linux kernel’s mlx5_ib MR deregistration deadlock. The description shows a flow where holding the mutex umem_mutex during dereg_mr() can lead kzalloc() to trigger reclaim paths (fs_reclaim, mmu_notifier_invalidate_range_start), which in turn calls mlx5_ib_invalidate_ra...
