sssd

A memory management flaw exists in SSSD when the autofs responder service is enabled. Memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this by maintaining an open connection and repeatedly submitting valid requests, causing memory exhaustion and a Denial of Service (DoS). The vulnerability has a medium severity with a CVSS score of 5.5.
