Title
Sssd: sssd: denial of service via unprivileged autofs cache invalidation
Summary
A flaw was found in SSSD. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading to a Denial of Service (DoS) from degraded automount availability and elevated resource consumption.

Where disabling the responder is not possible, restricting access to the autofs responder socket (for example via socket permissions or limiting which local UIDs may connect) so that only the intended trusted clients can reach it also reduces exposure before a fix is available."
