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...
