CVE-2022-50415

CVE-2022-50415 affects the Linux kernel on the parisc architecture, where start_task() calls create_singlethread_workqueue() without validating its return value. If the call returns NULL, a null pointer dereference can occur later in queue_delayed_work/on and __queue_work, accessing wq->flags....

CVE-2022-50382 padata: Always leave BHs disabled when running ->parallel()

In the Linux kernel, the following vulnerability has been resolved: padata: Always leave BHs disabled when running -parallel A deadlock can happen when an overloaded system runs -parallel in the context of the current task: padatadoparallel -parallel pcryptaeadenc/dec padatadoserial...

CVE-2022-50382

CVE-2022-50382 refers to a Linux kernel fix for a deadlock involving padata parallelization when BHs are enabled during the serial path. The issue occurs in padata_do_serial where a spin_lock on reorder->lock could be taken with BHs still on, enabling a deadlock on overload. The fix ensures BH...

PT-2025-38432

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The start task function in the Linux kernel may experience a null pointer dereference. This occurs because the return value of create singlethread workqueue is not checked, potentially...

PT-2025-40641

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw within the cnic module, specifically in the cnic delete task function, that can lead to a use-after-free condition. The issue arises from the use of canc...

Dragonfly incorrectly handles a task structure’s usedTrac field

Impact The processPieceFromSource method figure 4.1 is part of a task processing mechanism. The method writes pieces of data to storage, updating a Task structure along the way. The method does not update the structure’s usedTraffic field, because an uninitialized variable n is used as a guard to...

CVE-2025-59348

CVE-2025-59348 affects Dragonfly, an open-source P2P file distribution and image acceleration system. The vulnerability lies in the processPieceFromSource method, where an uninitialized variable n is used as a guard for the AddTraffic call instead of the actual result.Size, causing the structure’...

In the Linux kernel, the following vulnerability has been resolved: powerpc: Don't try to copy PPR for task with NULL ptregs powerpc sets up PFKTHREAD and PFIOWORKER with a NULL ptregs, which from my arguably very short checking is not commonly done for other archs. This is fine, except when...

kernel: posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

A race condition was found in the Linux kernel’s POSIX CPU timer handling, where handleposixcputimers may run concurrently with posixcputimerdel on an exiting task which could result in use-after-free scenarios. An attacker with local user access could use this flaw to crash or escalate their...
