CVE-2026-16935

IBM AIX versions 7.2 and 7.3, as well as IBM PowerVM VIOS 4.1, are vulnerable to a time-of-check to time-of-use (TOCTOU) race condition that could enable local attackers to escalate their privileges. This vulnerability poses a significant risk, as it allows unauthorized users to execute commands with elevated permissions, potentially compromising system integrity and confidentiality. Organizations using these IBM products should prioritize patching to mitigate the risk of exploitation.
