CVE-2026-20879: Denial of Service in Intel(R) Data Center Graphics Driver for VMware ESXi software
CVE-2026-20879 is a high-severity vulnerability in the Intel Data Center Graphics Driver for VMware ESXi software versions before 2. 0. 2. It involves an out-of-bounds write in the driver running in Ring 1 (device driver level), which may allow a privileged local attacker to cause denial of service and data corruption. The attack requires local privileged access but no user interaction or special internal knowledge. The vulnerability impacts system integrity and availability but does not affect confidentiality. No official patch or remediation guidance is currently confirmed.
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.
