CVE-2014-9066

Publication date 9 December 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
