CVE-2014-8867 is a vulnerability of currently unknown severity. The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O (MMIO) emulated in the hypervisor, which allows local HVM guests to cause a denial of service (host crash) via unspecified vectors.. EPSS estimates a 0.46% chance of exploitation in the next 30 days.
