CVE-2026-23053 Details
Description
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.
A deadlock vulnerability has been identified in the Linux kernel's NFSv4.1 implementation, specifically in versions prior to the latest patch. The issue arises during state recovery, where the process waits on 'kthreadd' to reclaim memory by calling 'nfs_release_folio()'. However, this release function cannot proceed because state recovery is still needed, leading to a deadlock. The vulnerability occurs in the NFS module of the Linux kernel.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability. Instructions for downloading the patched version can be found in the Linux kernel repository.
