CVE-2026-116497 · Gssproxy: gssproxy: null pointer dereference in gssx_init_sec_context crashes daemon

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A NULL pointer dereference vulnerability was found in gssproxy. When a GSSX_INIT_SEC_CONTEXT request is received with the target_name field absent, the daemon dereferences the resulting NULL pointer and crashes. The request requires no authentication, allowing any local user to crash the gssproxy daemon via its Unix socket. The daemon does not automatically restart, resulting in a persistent denial of service that also affects dependent services such as Kerberized NFS and IdM.
