What is CVE-2026-20713?
A flaw in the control flow implementation within certain firmware for Intel Xeon processors poses a risk of potential privilege escalation. This vulnerability allows a system software adversary with privileged user access to exploit high complexity attack scenarios, potentially resulting in unauthorized privilege elevation. Importantly, this vulnerability might be exploited locally and does not necessitate user interaction or specialized internal knowledge. While it does not significantly impact confidentiality or availability directly, it presents serious implications for system integrity.
Affected Version(s)
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.
