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.

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.

Improper buffer restrictions in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local 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.

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

Hardware debug modes and processor INIT setting that allow override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel(R) TXT may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

Improper input validation in the Intel(R) SGX SDK applications compiled for SGX2 enabled processors may allow a privileged user to potentially escalation of privilege via local access.

Hardware allows activation of test or debug logic at runtime for some Intel(R) processors which may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

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

Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

A vulnerability was found in Intel's implementation of RAPL (Running Average Power Limit). An attacker with a local account could query the power management functionality to intelligently infer SGX enclave computation values by measuring power usage in the RAPL subsystem.

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.
