Descriptions

An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the 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 acceso a memoria fuera de límites (OOB) en el controlador vmwgfx en el archivo drivers/gpu/vmxgfx/vmxgfx_kms.c en el componente GPU en el 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)

An out-of-bounds memory write vulnerability was found in the Linux kernel's vmwgfx driver in vmw_kms_cursor_snoop due to a missing check of a memcpy length. This flaw allows a local, unprivileged attacker with access to either the /dev/dri/card0 or /dev/dri/rendererD128 and able to issue an ioctl() on the resulting file descriptor, to crash the system, causing a denial of service.
