VIOS (PowerVM Virtual I/O Server) is an IBM virtualization product with a critical security track record. A cluster of high-to-critical RCE and privilege escalation flaws was discovered in August 2026, stemming from improper pointer validation and process controls.
PROFILE
Categoryhardware/softwareWhat they doVIOS is a product, specifically the PowerVM Virtual I/O Server, developed by IBM for virtualization infrastructure.
SECURITY POSTURE
VIOS has a poor security posture, evidenced by a critical RCE vulnerability (CVE-2026-16919) and a cluster of high-severity remote code execution and privilege escalation flaws discovered in August 2026 affecting AIX 7.2/7.3 and VIOS 4.1.
Notable failures
- CVE-2026-16919 critical RCE
- CVE-2026-17436 high RCE
- CVE-2026-18832 high RCE
Patterns: repeated unpatched remote code execution vulnerabilities; improper pointer validation and process controls
