medium Tenable Self-Hosted Container Security Plugin ID 463586

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: padata: do not leak refcount in
 reorder_work A recent patch that addressed a UAF introduced a reference count leak: the parallel_data
 refcount is incremented unconditionally, regardless of the return value of queue_work(). If the work item
 is already queued, the incremented refcount is never decremented. Fix this by checking the return value of
 queue_work() and decrementing the refcount when necessary. Resolves: Unreferenced object
