CVE-2024-31145

Name of the Vulnerable Software and Affected Versions Xen (affected versions not specified)

Description The issue is related to flawed error handling in the logic establishing mappings for Reserved Memory Regions (RMRR) in Intel VT-d or Unity Mapping ranges for AMD-Vi. This flaw can result in mappings remaining in place when they should have been removed, allowing respective guests to gain access to memory regions they are not supposed to have access to. The precise purpose of these regions is unknown, and they are typically used for platform tasks such as legacy USB emulation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
