CVE-2026-98989

A flaw was found in the Linux kernel. A local user can exploit this vulnerability by performing recursive bind mounts containing mount namespace file descriptors, bypassing loop detection mechanisms. This issue creates cyclical mount references, preventing the kernel from freeing associated namespaces and mount data. Consequently, repeated exploitation leads to unbounded kernel memory consumption, resulting in a Denial of Service (DoS).
