Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A reference count leak was introduced in the Linux kernel due to a recent patch that addressed a Use After Free (UAF) issue. 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. This issue can lead to an unreferenced object, as seen in the provided hex dump and backtrace.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
