CVE-2026-90036

This is a use-after-free in the Linux kernel NFSD (NFS server daemon) subsystem. A bare lock owner holds a raw pointer to its nfs4_client without a reference keeping the client alive. When the per-net laundromat reaps a blocked lock, the owner reference is dropped via flc_owner, and a concurrent ...
