## Description:

This update for ucode-intel fixes the following issues:

  * Intel CPU Microcode was updated to the 20250812 release (bsc#1248438)

    * CVE-2025-20109: Improper Isolation or Compartmentalization in the stream cache mechanism for some Intel Processors may allow an authenticated user to potentially enable escalation of privilege via local access.
    * CVE-2025-22840: Sequence of processor instructions leads to unexpected behavior for some Intel Xeon 6 Scalable processors may allow an authenticated user to potentially enable escalation of privilege via local access
    * CVE-2025-22839: Insufficient granularity of access control in the OOB-MSM for some Intel Xeon 6 Scalable processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.
    * CVE-2025-22889: Improper handling of overlap between protected memory ranges for some Intel Xeon 6 processor with Intel TDX may allow a privileged user to potentially enable escalation of privilege via local access.
    * CVE-2025-20053: Improper buffer restrictions for some Intel Xeon Processor firmware with SGX enabled may allow a privileged user to potentially enable escalation of privilege via local access.
    * CVE-2025-26403: Out-of-bounds write in the memory subsystem for some Intel Xeon 6 processors when using Intel SGX or Intel TDX may allow a privileged user to potentially enable escalation of privilege via local access.
    * CVE-2025-32086: Improperly implemented security check for standard in the DDRIO configuration for some Intel Xeon 6 Processors when using Intel SGX or Intel TDX may allow a privileged user to potentially enable escalation of privilege via local access.
