Race Condition in 3rd Gen Intel Xeon Scalable Processors

Publication date: 2026-08-11

Last updated on: 2026-11-02

Assigner: Intel Corporation

Description

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.

The vulnerability may lead to system unavailability (denial of service) due to race conditions in hardware logic. It does not directly impact confidentiality or integrity but could disrupt system operations, potentially causing downtime or service interruptions.

Compliance Impact

This vulnerability primarily impacts system availability due to potential denial of service conditions. It does not directly affect confidentiality or integrity. Compliance impact depends on whether availability is a critical requirement for standards like GDPR or HIPAA in the affected system context.

Mitigation Strategies

Apply Intel's official microcode updates or firmware patches for affected processors. Monitor Intel's security advisories for updates. Ensure system availability is prioritized due to high impact on availability.
