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

Description The issue is related to the do tmem destroy pool function in the Transcendent Memory (TMEM) component, which does not properly validate pool ids. This allows local guest OS users to cause a denial of service, resulting in memory corruption and host crash, or potentially execute arbitrary code.

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