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

Description A deadlock can occur when an overloaded system runs ->parallel() in the context of the current task. This issue arises from bottom halves (BHs) not being disabled in do serial, leading to a potential deadlock situation when an interrupt occurs during the execution of padata do serial while the reorder->lock is held. The vulnerability is related to the padata do parallel function, which calls ->parallel(), which in turn calls pcrypt aead enc/dec and padata do serial.

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