A flaw was found in SSSD (System Security Services Daemon). When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without completing them, causing unbounded memory consumption.
This memory exhaustion can lead to a Denial of Service (DoS) by degrading or terminating SSSD authentication services.
