CVE-2022-48887

Local system crash via vmwgfx resource race

Published Aug 21, 2024 · Updated Aug 5, 2026

A race condition in Linux kernel 4.20 through 6.1.6 and 6.2-rc1 through 6.2-rc3 allows local users to crash the system. The vmwgfx user-resource lookup path uses buggy RCU synchronization, allowing concurrent command submission and resource access to race over shared objects. A local user must be able to open a vmwgfx DRM render node; concurrent commands can produce a kernel oops, crash applications, or interrupt the system.
