CVE-2026-16874
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
IBM AIX 7.2, 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to obtain root privileges due to improper enforcement of RBAC authentication roles.
Risk Assessment
A local attacker could gain full control of the system, potentially leading to complete compromise.
Recommendation
Install security updates from IBM for affected versions.
