CVE-2026-90037

CVE-2026-90037 is a use-after-free in the Linux kernel's NFSD (NFS server daemon) component. An nfs4_openowner left on the close_lru list after its final CLOSE holds a raw pointer to its nfs4_client. When the laundromat reaps timed-out entries and drops client_lock, a concurrent force_expire_clie...
