CVE-2026-16837
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk18th percentile - higher than 18% of all known CVEs
Summary
IBM AIX 7.2, 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to improper handling of a missing SSL client certificate.
Risk Assessment
The attack could cause service unavailability, potentially disrupting organizational operations.
Recommendation
Apply security patches from IBM and properly configure client certificate requirements.
