CVE-2026-20707: Denial of Service in 3rd Gen Intel(R) Xeon(R) Scalable Processors
Hardware logic contains race conditions for some 3rd Gen Intel(R) Xeon(R) Scalable Processors within Ring 3: unprivileged software may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability involves race conditions in the hardware logic of certain 3rd Gen Intel Xeon Scalable Processors within Ring 3. An unprivileged, authenticated local attacker could exploit these race conditions to cause a denial of service, impacting system availability. The attack complexity is high and does not require user interaction. There is no impact on confidentiality or integrity. The CVSS 4.0 base score is 6.8, reflecting medium severity. No official remediation or patch information is currently available.
Potential Impact
The vulnerability allows a local, authenticated attacker with unprivileged access to cause a denial of service, resulting in high impact to system availability. There is no impact on confidentiality or integrity of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation has been published at this time.
