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

Description A issue in the Linux kernel has been identified where a wiphy work can be queued from the moment the wiphy is allocated and initialized. If wiphy free is called before the rdev::wiphy work had a chance to run, the wiphy memory will be freed, and then when it eventually gets to run it'll use invalid memory. This is resolved by canceling the work before freeing the wiphy.

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