Oct 13 EXPLOIT PUBLISHED — CVE-2026-104045 (Red Hat Enterprise Linux 10). Public exploit reference added.
Description
A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race condition in the autofs responder between asynchronous enumeration completion and map invalidation. By repeatedly sending concurrent map enumeration and invalidation requests, an attacker can cause memory to leak, leading to excessive memory consumption that can disrupt or crash the autofs service.
