CVE-2026-20794: Escalation of Privilege in Intel(R) Data Center Graphics Driver for VMware ESXi software
Buffer overflow for the Intel(R) Data Center Graphics Driver for VMware ESXi software before version 2.0.2 within Ring 1: Device Drivers may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the Intel Data Center Graphics Driver for VMware ESXi software prior to version 2.0.2. It occurs within Ring 1 device drivers and may enable escalation of privilege by a system software adversary who already has privileged user access. The attack requires local access but no user interaction or special internal knowledge. The CVSS 4.0 score is 9.3 (critical), reflecting high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available to confirm remediation status.
Potential Impact
Successful exploitation could allow an attacker with privileged user access to escalate privileges further, potentially compromising system confidentiality, integrity, and availability at high levels. This could lead to unauthorized code execution and control over the affected system components.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit privileged user access and monitor for unusual local activity related to the Intel Data Center Graphics Driver on VMware ESXi hosts.
