CVE-2020-12384

Local privilege escalation via undisclosed access-control flaw

Published Feb 17, 2021 · Updated Aug 4, 2024

Improper access control in Intel Graphics Drivers before 26.20.100.8476 allows local users to escalate privileges via local access. Intel has not published the affected code locus or the operation that incorrectly permits access to a protected resource. A low-privilege authenticated local account is required, and Intel's assessment limits direct impact to integrity within the same security authority.
