CVE-2023-45174

Local privilege escalation or service interruption

Published Dec 13, 2023 · Updated Aug 2, 2024

Local privilege escalation and denial of service in IBM AIX 7.2 and 7.3 and VIOS 3.1 allow local users to gain privileges or interrupt service. The qdaemon command is the affected locus, but IBM has not disclosed the input or faulty operation that triggers the privilege change or service interruption. Exploitation requires preexisting privileged local access, and the reported consequences are higher privileges or disruption of printer services.
