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.

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

A flaw was found in hw. The Intra-mode BTI refers to a variant of Branch Target Injection aka SpectreV2 (BTI) where an indirect branch speculates to an aliased predictor entry for a different indirect branch in the same predictor mode, and a disclosure gadget at the predicted target transiently executes. These predictor entries may contain targets corresponding to the targets of an indirect near jump, indirect near call, and near return instructions, even if these branches were only transiently executed. The managed runtimes provide an attacker with the means to create the aliasing required for intra-mode BTI attacks.

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 potential domain bypass transient execution vulnerability was discovered on some Intel Atom® processors that uses a microarchitectural incidental channel. Currently this channel can reveal supervisor data in the L1 cache and the contents of recent stores. As a consequence, this issue may allow an authenticated user to potentially enable information disclosure via local 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.
