CVE-2026-20713: Escalation of Privilege in 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
CVE-2026-20713 is an escalation of privilege vulnerability in some firmware implementations for Intel Xeon processors. It requires a system software adversary with privileged user access and a high complexity attack to exploit. The attack is local, requires no user interaction, and does not require special internal knowledge. While the initial impact on confidentiality, integrity, and availability is none, exploitation may lead to high confidentiality and integrity impacts on the system. No affected versions or patch information are provided. The CVSS score rates this as a medium severity issue.
AI Analysis
Technical Summary
This vulnerability involves an always-incorrect control flow implementation in certain firmware for Intel Xeon processors, which may allow escalation of privilege. Exploitation requires a privileged user and a complex local attack without user interaction or special internal knowledge. Although the initial vulnerability does not directly impact confidentiality, integrity, or availability, successful exploitation could result in high confidentiality and integrity impacts on the system. No specific affected versions or remediation details are available.
Potential Impact
The vulnerability may allow a local attacker with privileged user access to escalate privileges, potentially leading to high confidentiality and integrity impacts on the affected system. There is no direct impact on availability. The attack complexity is high, and no user interaction is required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation details are provided at this time.
