CVE-2026-89662
A flaw was found in the Linux kernel's Network File System Daemon NFSD. During client teardown, a race condition can occur where a lock owner is freed while still being referenced, leading to a use-after-free vulnerability. This can result in a NULL dereference, potentially causing a system crash...

CVE-2026-89662
This is a use-after-free vulnerability in the Linux kernel's NFSD (NFS server daemon) during client teardown. When __destroy_client() releases a client's owners, a lock owner whose only reference is a blocked lock remains on the owner hash table. Because client_has_state() does not count such a b...
