CVE-2026-23053

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFS: Fix a deadlock involving nfs_release_folio()<br /> <br /> Wang Zhaolong reports a deadlock involving NFSv4.1 state recovery<br /> waiting on kthreadd, which is attempting to reclaim memory by calling<br /> nfs_release_folio(). The latter cannot make progress due to state<br /> recovery being needed.<br /> <br /> It seems that the only safe thing to do here is to kick off a writeback<br /> of the folio, without waiting for completion, or else kicking off an<br /> asynchronous commit.
