Summary
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.
Risk Assessment
Risk of privilege escalation, potentially leading to compromise of system confidentiality and integrity.
Recommendation
Update Intel Xeon processor firmware to the latest version with security fixes.
Original NVD description (English source)
Always-incorrect control flow implementation in some firmware for some Intel(R) Xeon(R) processors may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
