CVE-2012-6030

Name of the Vulnerable Software and Affected Versions Xen versions 4.0 through 4.2

Description The issue is related to the do tmem op function in the Transcendent Memory (TMEM) component, which allows local guest OS users to cause a denial of service (host crash) and possibly have other unspecified impacts. This is due to broken locking checks in an error path.

Recommendations For Xen versions 4.0 through 4.2, consider restricting access to the do tmem op function as a temporary workaround until a patch is available.
