Описание
An integer overflow 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).
An integer overflow was found in the Linux kernel's vmwgfx driver. This flaw allows a local, unprivileged attacker with access to either /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.
Отчет
Systems making use of the vmwgfx driver are potentially affected by this flaw; systems without the vmwgfx driver loaded are not affected by this flaw.
Меры по смягчению последствий
To mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the vmwgfx kernel module. For instructions relating to blacklisting a kernel module, please see https://access.redhat.com/solutions/41278.
