CVE-2020-0520

Privilege escalation or crash via path traversal

Published Mar 12, 2020 · Updated Aug 4, 2024

Path traversal in igdkmd64.sys in Intel Graphics Drivers allows local users to gain privileges or crash Windows systems. Affected releases are those before 15.33.49.5100, 15.36.38.5117, 15.40.44.5107, and 15.45.30.5103; Intel has not disclosed the affected routine or pathname source. A locally authenticated user must reach the kernel-mode driver; successful exploitation enables privilege escalation, limited disclosure, or a system crash.
