1. 漏洞描述

This is a tool to transform and deploy microcode update for x86 CPUs.

Security Fix(es):

Protection mechanism failure in some 3rd and 4th Generation Intel(R) Xeon(R) Processors when using Intel(R) SGX or Intel(R) TDX may allow a privileged user to potentially enable escalation of privilege via local access.(CVE-2023-22655)

Information exposure through microarchitectural state after transient execution from some register files for some Intel(R) Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.(CVE-2023-28746)

Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2023-38575)

Protection mechanism failure of bus lock regulator for some Intel(R) Processors may allow an unauthenticated user to potentially enable denial of service via network access.(CVE-2023-39368)

Incorrect calculation in microcode keying mechanism for some Intel(R) Xeon(R) D Processors with Intel(R) SGX may allow a privileged user to potentially enable information disclosure via local access.(CVE-2023-43490)

Hardware logic contains race conditions in some Intel(R) Processors may allow an authenticated user to potentially enable partial information disclosure via local access.(CVE-2023-45733)

Improper input validation in some Intel(R) TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enable escalation of privilege via local access.(CVE-2023-45745)

Sequence of processor instructions leads to unexpected behavior in Intel(R) Core(TM) Ultra Processors may allow an authenticated user to potentially enable denial of service via local access.(CVE-2023-46103)

Improper input validation in some Intel(R) TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enable escalation of privilege via local access.(CVE-2023-47855)
