CVE-2024-31145
CVE-2024-31145 is confirmed in connected advisories as a Xen/Xen-related vulnerability affecting the x86 IOMMU identity mapping for PCI devices using Reserved Memory Regions (RMRR) or similar mappings. The flaw allows a guest VM to retain access to memory regions that should be removed, enabling ...
CVE-2024-31145 error handling in x86 IOMMU identity mapping
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 ...

CVE-2021-26367
CVE-2021-26367 describes a vulnerability where an attacker with local access could cause a misconfiguration of the Trusted Memory Regions (TMRs) on AMD platforms with AMD Secure Processor (ASP). The root cause is misconfiguration of TMR address ranges, potentially enabling an attacker to set an a...
PT-2024-6385
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 mapping...
