CVE-2022-49315

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

Description A deadlock issue exists in the Linux kernel, specifically in the rtllib beacons stop() function. This occurs when two threads attempt to access the ieee->beacon lock simultaneously, causing one thread to block indefinitely. The issue arises from the use of del timer sync() within the protection of spin lock irqsave(), which prevents the timer handler from obtaining the necessary lock.

Recommendations For the affected Linux kernel version, apply the patch that extracts del timer sync() from the protection of spin lock irqsave() to resolve the deadlock issue in rtllib beacons stop().
