  * New upstream microcode datafile 20250512
    - Mitigations for INTEL-SA-01153 (ITS: Indirect Target Selection):
      CVE-2024-28956: Processor may incompletely mitigate Branch Target
      Injection due to indirect branch predictions that are not fully
      constrained by eIBRS nor by the IBPB barrier.  Part of the "Training
      Solo" set of vulnerabilities.
    - Mitigations for INTEL-SA-01244:
      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.
    - Mitigations for INTEL-SA-01247:
      CVE-2024-43420, CVE-2025-20623: Exposure of sensitive information
      caused by shared microarchitectural predictor state that influences
      transient execution for some Intel Atom and some Intel Core
      processors (10th Generation) may allow an authenticated user to
      potentially enable information disclosure via local access.
      CVE-2024-45332 (Branch Privilege Injection): 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.
    - Mitigations for INTEL-SA-01322:
      CVE-2025-24495 (Training Solo): 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 (IBPB bypass)
      CVE-2025-20012 (Training Solo): Incorrect behavior order for some
      Intel Core Ultra Processors may allow an unauthenticated user to
      potentially enable information disclosure via physical access.
    - Improved fix for the Vmin Shift Instability for the Intel Core 13th
      and 14th gen processors under low-activity scenarios (sig 0xb0671).
      This microcode update is supposed to be delivered as a system
      firmware update, but according to Intel it should be effective when
      loaded by the operating system if the system firmware has revision
      0x12e.
    - Fixes for unspecified functional issues on several processor models
