CVE-2026-89668

A flaw was found in the nfsd component of the Linux kernel. The nfsddebugfsinit function is called before nfsd4initslabs. If the slab allocation fails, the nfsddebugfsexit cleanup function is bypassed, leaving orphaned debugfs files with stale function pointers. This can lead to a use-after-free...
