Description:
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\xae 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\xae Xeon\xae 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\xae Xeon\xae 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\xae Xeon\xae 6 processor with Intel\xae TDX may allow a privileged user to
potentially enable escalation of privilege via local access.
(CVE-2025-22889)
Improper buffer restrictions for some Intel\xae Xeon\xae 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\xae Xeon\xae 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\xae Xeon\xae
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\xae Xeon\xae 6
processors when using Intel\xae SGX or Intel\xae 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\xae Xeon\xae 6 Processors when using Intel\xae SGX
or Intel\xae TDX may allow a privileged user to potentially enable
escalation of privilege via local access. (CVE-2025-32086)
