CVE-2020-0501

Authenticated local denial of service via buffer overflow

Published Mar 12, 2020 · Updated Aug 4, 2024

A buffer overflow in Intel Graphics Drivers before 26.20.100.6912 allows local users to cause denial of service via local access. Intel identifies the locus only as a buffer in the graphics driver and does not publish the specific function or input path. An authenticated local user must reach the affected driver interface; the reported consequence is service interruption without stated confidentiality or integrity impact.
