PT-2025-37511

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A flaw exists in the Linux kernel's Xen/gntdev component that can lead to grant references being leaked. This occurs when a grant mapping operation fails partially, resulting in...

SUSE CVE-2021-28698

long running loops in grant table handling In order to properly monitor resource use, Xen maintains information on the grant mappings a domain may create to map grants offered by other domains. In the process of carrying out certain actions, Xen would iterate over all such entries, including ones...

SUSE CVE-2022-23034

A PV guest could DoS Xen while unmapping a grant To address XSA-380, reference counting was introduced for grant mappings for the case where a PV guest would have the IOMMU enabled. PV guests can request two forms of mappings. When both are in use for any individual mapping, unmapping of such a...

DEBIAN-CVE-2021-26932

An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then...

Linux: No grant table and foreign mapping limits

ISSUE DESCRIPTION Virtual device backends and device models running in domain 0, or other backend driver domains, need to be able to map guest memory either via grant mappings, or via the foreign mapping interface. Inside Xen, mapped grants are tracked by the maptrack structure. The size of this...
