Intel Xeon 6 insufficient granularity of access control

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability classified as problematic has been found in Intel Xeon 6. This affects an unknown part. This manipulation causes insufficient granularity of access control. This vulnerability is tracked as CVE-2025-22839. The attack is only possible within the local network. No exploit exists.

Detailsinfo

A vulnerability classified as problematic was found in Intel Xeon 6 (version now known). Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. The CWE definition for the vulnerability is CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Insufficient granularity of access control in the OOB-MSM for some Intel(R) Xeon(R) 6 Scalable processors may allow a privileged user to potentially enable escalation of privilege via adjacent access.

The advisory is shared at intel.com. This vulnerability is known as CVE-2025-22839 since 01/16/2025. The exploitation appears to be difficult. Access to the local network is required for this attack to succeed. Additional levels of successful authentication are required for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/02/2025).
