Technical details
CWE-129 improper array index validation in the RTAS firmware-to-OS interface allows a local attacker with root/administrator privileges to send a malicious request that triggers a partition crash (denial of service). The vulnerability requires high privilege level (root) on the logical partition and local access; network attack is not possible. This is a denial-of-service condition with no data exposure or integrity compromise; affected partitions must be restarted manually.
