[ Description ]Official description

A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.
