CVE-2025-40110

Local system crash via invalid surface identifier

Published Nov 12, 2025 · Updated Nov 12, 2025

NULL pointer dereference in the Linux kernel vmwgfx driver allows local users to crash the system through a crafted SVGA command. vmw_cmd_res_check accepts SVGA3D_INVALID_ID as a valid no-surface value, but the cursor snooper dereferences the resulting null resource without verifying that a surface object exists. The path requires local low-privilege access and an active vmwgfx driver; successful exploitation interrupts the host through a kernel crash.
