A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in GPU component of Linux kernel with device file /dev/dri/renderD128 (or Dxxx). This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
