A use-after-free flaw was found in the Linux kernel’s vmw_execbuf_copy_fence_user function in drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c in vmwgfx. This flaw allows a local attacker with user privileges to cause a privilege escalation problem.
Mitigation for this issue is to skip loading the affected module vmwgfx onto the system until we have a fix available. This can be done by a blacklist mechanism and ensures the driver is not loaded at the boot time.
How do I blacklist a kernel module to prevent it from loading automatically?
