Cisco's Talos discovered a denial-of-service vulnerability in AMD's Radeon Software drivers. The CreateAllocation (CVE-2020-12911) can be used by an attacker to crash your system, but AMD believes further exploitation is not possible. The company plans to address the vulnerability in Q1 2021.
Our ecosystem collaborator Cisco Talos has published a new potential vulnerability in AMD graphics drivers, which may result in a blue screen. AMD believes that confidential information and long-term system functionality are not impacted, and that the user can resolve the issue by restarting the computer. AMD plans to issue updated graphics drivers to address the issue in the first quarter of 2021.

The research finds that a specially crafted D3DKMTCreateAllocation API request can cause an out-of-bounds read and denial of service (BSOD). This vulnerability can be triggered from non-privileged accounts.
