CVE-2014-7188 is a vulnerability of currently unknown severity. The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors.. EPSS estimates a 0.86% chance of exploitation in the next 30 days.
