Last modified
CVE-2014-9066 is a vulnerability of currently unknown severity. Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
