Local root escalation through undisclosed kernel flaw
Published Aug 26, 2021 · Updated Sep 17, 2024
Kernel privilege escalation in IBM AIX 7.1, 7.2, and VIOS 3.1 allows local users to obtain root privileges through local execution. IBM has not published the vulnerable kernel function, input path, or incorrect operation, so the code-level mechanism remains undisclosed. Exploitation requires code execution as a non-privileged local account and grants full root control over the affected system.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
