CVE-2026-33197: CWE-184: Incomplete List of Disallowed Inputs in AMI AptioV
AMI APTIOV contains a vulnerability in BIOS where a privileged user may cause the “Incomplete List of Disallowed Inputs” by local access. Successful exploitation of this vulnerability may lead to arbitrary code execution and impact system Confidentiality, Integrity, and Availability.
AI Analysis
Technical Summary
CVE-2026-33197 is a BIOS vulnerability in AMI AptioV where the BIOS does not fully restrict certain inputs, allowing a privileged local user to exploit this incomplete input validation. Successful exploitation can lead to arbitrary code execution with high impact on confidentiality, integrity, and availability of the system. The vulnerability requires local privileged access and does not involve user interaction. No official remediation or patch information is currently available.
Potential Impact
A privileged local attacker may execute arbitrary code at the BIOS level, potentially compromising the entire system's confidentiality, integrity, and availability. This could lead to persistent system compromise and control over hardware initialization processes.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict privileged local access to trusted users only.
