CVE-2024-31145

7.5 · HIGH
Published Sep 25, 2024 xen CWE-400 EPSS 0.23% (14th pctl)

Overview

CVE-2024-31145 is a high-severity vulnerability affecting xen xen. It was published on September 25, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

Certain PCI devices in a system might be assigned Reserved Memory

Regions (specified via Reserved Memory Region Reporting, "RMRR") for

Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used

for platform tasks such as legacy USB emulation.

Since the precise purpose of these regions is unknown, once a device

associated with such a region is active, the mappings of these regions

need to remain continuouly accessible by the device. In the logic

establishing these mappings, error handling was flawed, resulting in

such mappings to potentially remain in place when they should have been

removed again. Respective guests would then gain access to memory

regions which they aren't supposed to have access to.

Remediation

Check the references section for vendor advisories and patches from xen. Update xen to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
