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

Description A memory leak issue has been resolved in the Linux kernel. The issue occurs when a freeze notification is cleared with BC CLEAR FREEZE NOTIFICATION before calling binder freeze notification done(), causing the work to remain queued in proc->delivered freeze and leading to a memory leak when the process exits. The patch fixes the leak by ensuring that any pending entries in proc->delivered freeze are freed during binder deferred release().

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