Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the ieee80211 tx dequeue() function related to spinlock handling. An asynchronous interrupt can occur between the spin lock() and spin unlock() operations, potentially leading to a deadlock if the interrupt routine attempts to lock the same local->queue stop reason lock again. This can cause a CPU reset or a system hang, particularly in single CPU/core scenarios. The issue arises from a missing interrupt disable around the remaining spin lock(&local->queue stop reason lock) operation. The trace indicates a potential unsafe locking scenario where a deadlock can occur.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
