CVE-2026-89694

A flaw was found in the Linux kernel's NFSv4.2 server nfsd. An authenticated NFSv4.2 client could exploit a vulnerability in the managecpntfstate function by guessing a state identifier. This improper ownership check allows the client to cancel and free another client's copy-notify stateid, leadi...

CVE-2026-89663

A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability arises from improper handling of "copy-notify stateids" during their revocation. When a stateid's reference is dropped without unlinking it, the memory can be freed while still in use by a reader, leading t...
