Descriptions

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).

Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en el controlador vmwgfx en el archivo drivers/gpu/vmxgfx/vmxgfx_execbuf.c en el componente GPU del kernel de Linux con el archivo de dispositivo "/dev/dri/renderD128 (o Dxxx)". Este fallo permite a un atacante local con una cuenta de usuario en el sistema conseguir privilegios, causando una denegación de servicio (DoS)

A NULL pointer dereference issue was found in the Linux kernel's vmwgfx driver in vmw_cmd_dx_define_query. 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, causing a denial of service.
