CVE-2025-40212
Linux Kernel NFS Refcount Leak Vulnerability
Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.
A vulnerability in the Linux kernel's NFS server could allow a denial of service if a client sends a malformed filehandle. This is unlikely in normal usage, as it requires a client to deliberately synthesize an incorrect filehandle.
