CVE-2020-12960

Local denial of service via malformed InputBuffer

Published Nov 15, 2021 · Updated Sep 17, 2024

Improper input validation in AMD Radeon Software before 21.4.1 allows local users to cause a denial of service through amdfender.sys. Within amdfender.sys, the InputBuffer handling path fails to validate supplied data before processing it; AMD has not disclosed the specific request or invalid operation. Low-privileged local access is required; Radeon Pro Software for Enterprise before 21.Q2 is also affected, and the documented consequence is limited to service interruption.
