CVE-2024-56714

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

Description The issue involves destroying a workqueue more than once in the Linux kernel, which could cause an error. This problem arises from certain firmware error handling paths. A specific case where this issue occurred was during an AER event, where handlers were called in a way that led to ionic reset prepare() and ionic dev teardown() being called twice in a row. The second call attempted to destroy the workqueue again, but since it was already destroyed, destroy workqueue() failed due to a bad pointer. This was not caught in initial AER handler testing because a private workqueue was not being used at that time.

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