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 oxu bus suspend() function. This occurs due to a lock being held in one thread while waiting for a timer to stop, and the timer handler also requiring the same lock, resulting in a block. The issue arises from the use of del timer sync() within the protection of spin lock irq(), preventing the timer handler from obtaining the necessary lock.

Recommendations For the affected Linux kernel versions, apply the patch that extracts del timer sync() from the protection of spin lock irq() to resolve the deadlock issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
