## Description:
This update for microcode_ctl fixes the following issues:
Intel CPU Microcode was updated to the 20250512 release (bsc#1243123)
* CVE-2024-28956: Exposure of Sensitive Information in Shared
Microarchitectural Structures during Transient Execution for some Intel
Processors may allow an authenticated user to potentially enable information
disclosure via local access.
* CVE-2025-20103: Insufficient resource pool in the core management mechanism
for some Intel Processors may allow an authenticated user to potentially
enable denial of service via local access.
* CVE-2025-20054: Uncaught exception in the core management mechanism for some
Intel Processors may allow an authenticated user to potentially enable
denial of service via local access.
* CVE-2024-43420: Exposure of sensitive information caused by shared
microarchitectural predictor state that influences transient execution for
some Intel Atom processors may allow an authenticated user to potentially
enable information disclosure via local access.
* CVE-2025-20623: Exposure of sensitive information caused by shared
microarchitectural predictor state that influences transient execution for
some Intel Core processors (10th Generation) may allow an authenticated user
to potentially enable information disclosure via local access.
* CVE-2024-45332: Exposure of sensitive information caused by shared
microarchitectural predictor state that influences transient execution in
the indirect branch predictors for some Intel Processors may allow an
authenticated user to potentially enable information disclosure via local
access.
* CVE-2025-24495: Incorrect initialization of resource in the branch
prediction unit for some Intel Core Ultra Processors may allow an
authenticated user to potentially enable information disclosure via local
access.
* CVE-2025-20012: Incorrect behavior order for some Intel Core Ultra
Processors may allow an unauthenticated user to potentially enable
information disclosure via physical access.
* Updates for functional issues.
