Description The issue is related to an improper check for unusual or exceptional conditions when using Certificate Management Protocol Version 2 (CMPv2) auto re-enrollment. This allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS) by crashing the pkid process. The pkid process cannot handle an unexpected response from the Certificate Authority (CA) server, leading to a crash. A restart is required to restore services.
