A flaw was found in Intel graphics hardware (GPU) where a local attacker with the ability to issue commands to the GPU which could inadvertently lead to memory corruption and possibly privilege escalation.

The attacker could use the GPU blitter to perform privilege MMIO operations not limited to the address space required to function correctly. This would expose the blitter to access kernel memory with a specially crafted request to the blitter.

Affected hardware:

- Ivy Bridge(Gen 7) and later, - Cherry Trail (Gen8) and newer mobile, desktop and embedded processors. - Intel Xeon E3-1200 v4 and later product families.
