Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.

Out-of-bounds read in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via adjacent access.

Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged 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.

A flaw was found in the implementation of Intel Transactional Synchronization Extensions (TSX) abortion where a local authenticated attacker with the ability to monitor execution time is able to infer TSX memory state by comparing abort execution times.

This could allow information disclosure via this observed sidechannel for any TSX transaction being executed while an attacker is able to observe abort timing.

Gather Date Sampling (GDS) is a transient execution side channel vulnerability affecting certain Intel processor. In this flaw, a local attack using gather instruction (load from memory) may infer stale data from previously used vector registers on the same physical core.

Improper initialization in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via physical access.

Improper isolation of shared resources in some Intel(R) Processors when using Intel(R) Software Guard Extensions may allow a privileged user to potentially enable information disclosure via local access.

A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read by another process or a CPU sibling. The highest threat from this vulnerability is data confidentiality where an attacker could read arbitrary data as it passes through the processor.

A flaw was found during cache eviction on some Intel processors which may allow a local attacker to infer cache contents and disclose information through this side-channel.
