Intel Xeon processors vulnerabilities

Some Intel(R) Xeon(R) processors contain an improper input validation vulnerability in firmware that may allow an escalation of privilege. A startup code and SMM adversary with a privileged user and a high complexity attack may enable data alteration. This requires local access but no user interaction. The vulnerability may impact system integrity (high), but not confidentiality or availability.

Improper access control in the firmware for Alias Checking Trusted Module for some Intel(R) Xeon(R) processors may allow privilege escalation. A privileged user with a high complexity attack may enable escalation. This may occur via local access without user interaction. Confidentiality and integrity impact are high.

Always-incorrect control flow implementation in Intel Xeon processor firmware may allow privilege escalation. A privileged attacker with a high complexity attack can escalate privileges via local access, without user interaction.
