kernel: vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query

A NULL pointer dereference issue was found in the Linux kernel's vmwgfx driver in vmwcmddxdefinequery. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, who can issue an ioctl on the resulting file descriptor, to crash the system, causi...
