**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The Linux kernel contains a deadlock issue involving NFSv4.1 state recovery. The deadlock occurs when `kthreadd` attempts to reclaim memory by calling the `nfs release folio()` function, which is blocked due to the need for state recovery. The issue involves waiting on `kthreadd` while state recovery is in progress, preventing `nfs release folio()` from making progress. A potential resolution involves initiating a writeback of the folio without waiting for completion or triggering an asynchronous commit. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
