CVE-2026-89707

A flaw was found in the Linux kernel's nfsd component. An authenticated Network File System NFS client can exploit this vulnerability by triggering a failed cross-mount operation through nfsdlookupdentry or the NFSv4 READDIR encode path. This leads to a reference count leak, which inflates mntcou...
