FKIE_CVE-2014-9066
Vulnerability from fkie_nvd - Published: 2014-12-09 23:59 - Updated: 2026-06-17 00:17
Severity
Summary
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.
