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.
