Improper access control in the Intel(R) Thunderbolt(TM) DCH drivers for Windows may allow an authenticated user to potentially enable escalation of privilege via local access.

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.

Insufficient memory protection in Intel(R) 6th Generation Core Processors and greater, supporting SGX, may allow a privileged user to potentially enable escalation of privilege via local access.

A flaw was found in the implementation of Intel Advanced Vector Extensions (AVX) where a local authenticated attacker with the ability to execute AVX instructions is able to gather AVX register state from previous AVX executions.

This could allow information disclosure of AVX register state.
