CVE-2024-35810

Local kernel compromise via cursor buffer race

Published May 17, 2024 · Updated Aug 5, 2026

Race condition in the Linux vmwgfx cursor-plane code allows local users to read and modify kernel memory through concurrent cursor updates. vmw_plane_state manages mapped buffer-object lifetimes itself, allowing cleanup to invalidate cursor memory while an atomic update still uses it. Access to the VMware guest DRM card node is required; winning the race exposes recycled kernel memory, corrupts kernel objects, or crashes the guest.
