Summary
microcode_ctl security update
Details

Security Fix(es):

Improper buffer restrictions for some Intel(R) Xeon(R) Processor firmware with SGX enabled may allow a privileged user to potentially enable escalation of privilege via local access.(CVE-2025-20053)

Improper Isolation or Compartmentalization in the stream cache mechanism for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.(CVE-2025-20109)

Missing reference to active allocated resource for some Intel(R) Xeon(R) processors may allow an authenticated user to potentially enable denial of service via local access.(CVE-2025-21090)

Insufficient granularity of access control in the OOB-MSM for some Intel(R) Xeon(R) 6 Scalable processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.(CVE-2025-22839)

Sequence of processor instructions leads to unexpected behavior for some Intel(R) Xeon(R) 6 Scalable processors may allow an authenticated user to potentially enable escalation of privilege via local access(CVE-2025-22840)

Improper handling of overlap between protected memory ranges for some Intel(R) Xeon(R) 6 processor with Intel(R) TDX may allow a privileged user to potentially enable escalation of privilege via local access.(CVE-2025-22889)
