CVE-2026-104037: Out-of-bounds read vulnerability

A flaw was found in SSSD. A local attacker can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process and result in a denial of service (DoS).
