CVE-2026-23053
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix a deadlock involving nfs_release_folio()
Wang Zhaolong reports a deadlock involving NFSv4.1 state recovery waiting on kthreadd, which is attempting to reclaim memory by calling nfs_release_folio(). The latter cannot make progress due to state recovery being needed.
It seems that the only safe thing to do here is to kick off a writeback of the folio, without waiting for completion, or else kicking off an asynchronous commit.
