CVE-2026-89696
CVE-2026-89696 affects the Linux kernel's NFS daemon (nfsd) when CONFIG_NFSD_V4_2_INTER_SSC is enabled. A NULL pointer dereference occurs in the nfsd kthread when a remote, unauthenticated client crafts an NFS COMPOUND request containing an inter-SSC COPY operation with an additional op (e.g., SE...

CVE-2026-89689 nfsd: don't free session slots that are still in use
In the Linux kernel, the following vulnerability has been resolved: nfsd: don't free session slots that are still in use nfsd4sequence can free the very slot it is currently processing. When the session shrinker has reduced setargetmaxslots below sefchannel.maxreqs, the shrink path checks three...
CVE-2026-89689
CVE-2026-89689 is a use-after-free vulnerability in the Linux kernel's NFS daemon (nfsd) , specifically in nfsd4_sequence(). When the session shrinker reduces the number of active slots, free_session_slots() may free a slot still in use by the current request or a concurrent thread, because seq-&...
