The do_tmem_get function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (CPU hang and host crash) via unspecified vectors related to a spinlock being held in the "bad_copy error path." 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

A guest virtual machine on vulnerable Xen hosts could crash or hang the underlying host through a TMEM flaw. The business concern is availability: one local guest user may disrupt other workloads sharing the same hypervisor. Exposure is most likely in legacy Xen 4.0-4.2 environments where TMEM is present. Modern supported Xen deployments are less likely exposed, but asset evidence is needed because the supplied affected-product metadata is incomplete. Treat this as a high-priority availability risk for any remaining legacy Xen estate. It is less urgent where Xen 4.0-4.2 is absent or retired, but confirmation should be explicit. Mitigation focus: Inventory Xen hypervisors and identify any 4.0, 4.1, or 4.2 systems.; Review Xen XSA-15 and distribution advisories for supported update guidance.; Prioritize remediation on multi-tenant or untrusted guest-hosting platforms..
