Summary
microcode_ctl security update
Details

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

Security Fix(es):

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)
