Description

The vmwgfx driver contains a local privilege escalation vulnerability that allows unprivileged users to gain access to files opened by other processes on the system through a dangling 'file' pointer. 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.
