Apple macOS up to 10.14.4 Microcode information disclosure

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.

No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project. The advisory points out:

Multiple information disclosure issues were addressed partially by updating the microcode and changing the OS scheduler to isolate the system from web content running in the browser. To completely address these issues, there are additional opt-in mitigations to disable hyper threading and enable microcode-based mitigations for all processes by default. Details of the mitigations can be found at https://support.apple.com/kb/HT210107.

The vulnerability scanner Nessus provides a plugin with the ID 209571 (Oracle Linux 8 : virt:kvm_utils3 (ELSA-2024-12792)), which helps to determine the existence of the flaw in a target environment. The commercial vulnerability scanner Qualys is able to test this issue with plugin 172312 (SUSE Enterprise Linux Security Update for qemu (SUSE-SU-2019:1243-1)).
