Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a use-after-free issue within the networking subsystem, specifically in the mscc ocelot component. The problem arises from a cyclic delayed work item where
cancel delayed work() may fail to cancel a work item if it is already executing. This can lead to the work item being rescheduled after the work queue has been destroyed, resulting in a use-after-free condition. The issue occurs because destroy workqueue() does not have visibility of the pending work item before it is rescheduled. Static analysis identified this flaw.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
