CVE-2012-6036: n/a vulnerability

The (1) memc_save_get_next_page, (2) tmemc_restore_put_page and (3) tmemc_restore_flush_page functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 do not check for negative id pools, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or possibly 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.

Security readout for executives and security teams

This is a Xen hypervisor flaw in Transcendent Memory handling. A user inside a guest operating system could trigger memory corruption that crashes the host, disrupting all affected virtual machines. The CVE also notes possible arbitrary code execution, but the provided sources do not describe exploit details or confirmed exploitation. Exposure is mainly legacy Xen environments running 4.0, 4.1, or 4.2, especially where guest users or tenant administrators are untrusted. Modern supported Xen deployments are less likely exposed, but inherited virtualization stacks and old appliance images should be checked. Treat this as high priority if any legacy Xen 4.0-4.2 hosts remain. The business risk is service disruption across hosted workloads, with possible deeper compromise noted but not substantiated in the bundle. Mitigation focus: Identify Xen hosts running versions 4.0, 4.1, or 4.2.; Review Xen XSA-15 and distribution advisories for fixed packages or upgrade paths.; Prioritize remediation for multi-tenant or untrusted-guest environments..
