**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a race condition in the `zswap writeback entry()` function, which can lead to a folio being stranded indefinitely. This occurs because ` read swap cache async()` returns a folio locked when it is newly allocated, and the folio is ref'd. The bug was discovered by code inspection and is unlikely to crash the system, but rather cause the folio to become stranded. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
