CVE-2015-2751

Name of the Vulnerable Software and Affected Versions Xen versions 4.3.x through 4.5.x

Description The issue allows remote domains with partial management control to cause a denial of service, resulting in a host lock, through unspecified domctl operations when toolstack disaggregation is used.

Recommendations For Xen versions 4.3.x through 4.5.x, as a temporary workaround, consider restricting access to domctl operations to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
