Host crash via malformed MAD pixel shader
Published Jan 25, 2020 · Updated Aug 4, 2024
Out-of-bounds read in AMD Radeon Software 19.10.1 allows attackers to crash a VMware host via a malformed guest pixel shader. ATIDXX64.DLL mishandles a crafted MAD instruction in the pixel-shader compilation path and performs an out-of-bounds read. Exploitation requires control of a Windows guest in VMware Workstation 15 with a host using the affected Radeon driver; the bounded result is a host-side crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
