CVE-2026-20794: Escalation of Privilege in Intel(R) Data Center Graphics Driver for VMware ESXi software
CVE-2026-20794 is a critical buffer overflow vulnerability in the Intel Data Center Graphics Driver for VMware ESXi software versions before 2.0.2. It allows a system software adversary with privileged user access to potentially escalate privileges via local code execution without user interaction. The vulnerability impacts confidentiality, integrity, and availability at a high level. Exploitation requires local access and privileged user status but no special internal knowledge or user interaction. No official patch or remediation guidance is currently confirmed.
AI Analysis
Technical Summary
This vulnerability is a buffer overflow in the Intel Data Center Graphics Driver for VMware ESXi software prior to version 2.0.2, occurring within Ring 1 device drivers. It permits escalation of privilege by enabling local code execution when combined with a privileged user and a low complexity attack. The CVSS 4.0 score is 9.3 (critical), reflecting high impact on confidentiality, integrity, and availability. The vulnerability requires local access and privileged user rights but no user interaction or special internal knowledge. No vendor advisory or patch information is currently available to confirm remediation status.
Potential Impact
Successful exploitation can lead to local code execution with escalated privileges, potentially compromising system confidentiality, integrity, and availability at a high level. This could allow an attacker with existing privileged access to gain further control over the system, impacting critical security properties.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict privileged user access and monitor for unusual local activity. Avoid running untrusted code with privileged access on affected versions. Do not assume the vulnerability is mitigated without vendor confirmation.
