The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations 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 an old Xen hypervisor flaw in Transcendent Memory control handling. A user inside a guest operating system could reach control operations that should have required higher privilege. Business urgency depends on whether legacy Xen 4.0, 4.1, or 4.2 hosts remain in use. Exposure is most likely on legacy Xen 4.0, 4.1, or 4.2 deployments where guests can use TMEM hypercalls. Risk is higher in multi-tenant or untrusted-guest environments. The provided data does not identify non-Xen affected products. Prioritize this as a legacy infrastructure risk. It is not KEV-listed in the provided data, but hypervisor privilege-boundary issues matter when untrusted guests share hosts. Remediation urgency should track whether affected Xen versions are still operating. Mitigation focus: Identify any Xen 4.0, 4.1, or 4.2 hosts still in service.; Review Xen XSA-15 and vendor advisories for supported fixes or configuration guidance.; Prioritize remediation for hosts running untrusted or multi-tenant guest workloads..
