Sequence of processor instructions leads to unexpected behavior for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege and/or information disclosure and/or denial of service via local access.

Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service via local access.

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.

Time-of-check time-of-use race condition in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

Out-of-bounds write in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local access.

Improper access control in the BIOS authenticated code module for some Intel(R) Processors may allow a privileged user to potentially enable aescalation of privilege via local 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.

Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

Insecure default variable initialization for the Intel BSSA DFT feature may allow a privileged user to potentially enable an escalation of privilege via local access.

Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure 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 computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.

This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition
