CVE-2025-38338

CVE-2025-38338 is a Linux kernel vulnerability affecting NFS read paths. A double-unlock in fs/nfs/read during truncation can cause a deadlock because folio_unlock() may be called twice, incorrectly clearing the PG_locked flag. This can lead to warnings in netfs_read_collection or to processes wa...
