The updated package updates AMD cpu microcode for processor family 19h, adds AMD cpu microcode for processor family 1ah and fixes security vulnerabilities for Intel processors: 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-2025-20109) 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-2025-22840) 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-2025-22839) 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-2025-22889) 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-2025-20053) Insufficient control flow management in the Alias Checking Trusted Module (ACTM) firmware for some Intel® Xeon® processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2025-24305) Missing reference to active allocated resource for some Intel® Xeon® processors may allow an authenticated user to potentially enable denial of service via local access. (CVE-2025-21090) 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-2025-26403) 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. (CVE-2025-32086)
