The do_mmu_update function in arch/x86/mm.c in Xen 3.2.x through 4.4.x does not properly manage page references, which allows remote domains to cause a denial of service by leveraging control over an HVM guest and a crafted MMU_MACHPHYS_UPDATE.

Security readout for executives and security teams

CVE-2014-9030 is a Xen hypervisor denial-of-service issue. A party controlling an HVM guest could trigger faulty page-reference handling and disrupt service on affected Xen hosts. The public bundle does not show data theft, guest escape, or active exploitation evidence. Exposure is most likely on virtualization platforms running Xen 3.2.x through 4.4.x, especially where HVM guests are operated by tenants or less-trusted users. Distribution packages referenced by Debian, Gentoo, and openSUSE advisories should be checked. Treat this as a legacy virtualization availability risk. It is most urgent for providers or environments hosting untrusted HVM guests. It does not currently warrant active-exploitation emergency handling based on the supplied sources. Mitigation focus: Review Xen XSA-113 and applicable distribution advisories for vendor-supported fixes.; Upgrade affected Xen packages or move to a supported corrected Xen release.; Prioritize hosts running untrusted or tenant-controlled HVM guests..
