Privileged denial of service via out-of-bounds write
Published May 12, 2026 · Updated May 12, 2026
Out-of-bounds write in Intel Data Center Graphics Driver for VMware ESXi before 2.0.2 allows local users with high privileges to corrupt data. Intel identifies the flaw only within Ring 1 device-driver code and does not disclose the affected function, buffer, or input that exceeds its bounds. High privileges are required; exploitation needs no user interaction and can corrupt data or interrupt the ESXi host and its dependent workloads.
