CVE-2020-12361

Service interruption via undisclosed use-after-free

Published Feb 17, 2021 · Updated Aug 4, 2024

Use-after-free in Intel Graphics Drivers before 15.33.51.5146 allows local users to interrupt graphics services through local access. Intel identifies a use-after-free but has not disclosed the affected function, object lifetime error, or attacker-controlled trigger. An authenticated local session is required, and the documented consequence is denial of service without a bounded crash or hang characterization.
