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 Input validation in firmware for some Intel(R) Converged Security and Management Engine before versions 15.0.45, and 16.1.27 may allow a privileged user to potentially enable denial of service via local access.

Improper access control in the Intel(R) CSME software installer before version 2239.3.7.0 may allow an authenticated user to potentially enable 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.

A flaw was found in Intel® VT-d products. Entries from the context cache on some types of context cache invalidations may not be properly invalidated which may allow an authenticated user to potentially enable escalation of privilege via local access. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

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.

Insecure inherited permissions in some Intel(R) PROSet/Wireless WiFi products on Windows 7 and 8.1 before version 21.40.5.1 may allow an authenticated user to potentially enable escalation of privilege via local access.

Load value injection in some Intel(R) Processors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. The list of affected products is provided in intel-sa-00334: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00334.html

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 key protection vulnerability in silicon reference firmware for Intel(R) Pentium(R) Processor J Series, Intel(R) Pentium(R) Processor N Series, Intel(R) Celeron(R) J Series, Intel(R) Celeron(R) N Series, Intel(R) Atom(R) Processor A Series, Intel(R) Atom(R) Processor E3900 Series, Intel(R) Pentium(R) Processor Silver Series may allow a privileged user to potentially enable denial of service via local access.
