CVE-2024-46710

Graphics interruption via cursor-buffer mapping race

Published Sep 13, 2024 · Updated Aug 5, 2026

Race condition in the Linux vmwgfx driver allows local users to disrupt graphics processing through concurrent cursor-buffer updates. The KMS cursor update and comparison paths share persistent reads without tracking map users, so one path unmaps the buffer while another still reads it. The attack requires low privileges and a high-complexity local race; successful execution feeds bogus contents to the update path, with only availability impact documented.
