CVE-2020-12365

Local denial of service via untrusted pointer dereference

Published Feb 17, 2021 · Updated Aug 4, 2024

Denial of service in Intel Graphics Drivers before 15.33.51.5146 allows local authenticated users to interrupt service via local access. The affected branches also include versions before 15.45.32.5145, 15.36.39.5144 and 15.40.46.5143, where a driver dereferences an untrusted pointer without safe validation. Exploitation requires an authenticated local account and can crash or hang graphics-driver processing, with availability impact and no reported confidentiality or integrity impact.
