CVE-2026-89661
CVE-2026-89661 is a use-after-free in the Linux kernel's NFSD (NFS server daemon) subsystem. Writing a filesystem path to /proc/fs/nfsd/unlock_filesystem calls nfsd4_cancel_copy_by_sb() before the nfsd_mutex is held and before the handler confirms the server is still running. After shutdown, nfs4...
