CVE-2026-89712

A use-after-free race condition in the Linux kernel's NFSD component affects nfsd4_ssc_expire_umount(). When this function drops nfsd_ssc_lock to release a source vfsmount, a concurrent NFS RPC thread can free a list entry that the iteration macro has cached as its next pointer, causing a subsequ...
