CVE-2026-20879: Denial of Service in Intel(R) Data Center Graphics Driver for VMware ESXi software
Out-of-bounds write for the Intel(R) Data Center Graphics Driver for VMware ESXi software before version 2.0.2 within Ring 1: Device Drivers may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. 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 (none), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability is an out-of-bounds write flaw 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 can be exploited by a system software adversary with privileged user access through a low complexity attack. Exploitation may lead to denial of service and data corruption, impacting system integrity and availability. The CVSS 4.0 base score is 8.3, reflecting high severity with local attack vector, low attack complexity, no user interaction, and high impact on integrity and availability. No vendor advisory or patch information is currently available to confirm remediation status.
Potential Impact
The vulnerability can cause denial of service and data corruption on affected systems, impacting system integrity and availability. Confidentiality is not affected. Exploitation requires local privileged access but no user interaction or special internal knowledge. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix or workaround is released, restrict privileged local access to trusted users only and monitor for unusual activity related to the Intel Data Center Graphics Driver on VMware ESXi hosts.
