CVE-2026-16819

IBM AIX versions 7.2 and 7.3, along with IBM PowerVM VIOS 4.1, are vulnerable to a time-of-check time-of-use race condition that could enable a local attacker to execute a denial of service and potentially compromise data integrity. Organizations using these systems should prioritize remediation efforts to mitigate the risk of exploitation, particularly those with sensitive data or critical operations relying on these platforms.
