CVE-2012-6035: Xen

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The do_tmem_destroy_pool function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly validate pool ids, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or execute arbitrary code via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others.

Affected products

• Xen Xen: version 4.0.0 only; version 4.1.0 only; version 4.2.0 only
