Name of the Vulnerable Software and Affected Versions Xen versions prior to 4.12

Description An issue in Xen on AMD x86 platforms allows guest OS users to potentially gain host OS privileges due to the unsafe combination of small IOMMU mappings into larger ones. This could enable an attacker to elevate their privileges.

Recommendations For Xen versions prior to 4.12, update to a version that includes the fix for this issue to prevent potential privilege escalation.
