CVE-2014-5147: Xen

Medium severity, CVSS 4.3. EPSS: 0.4% chance of exploitation in the next 30 days.

Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process.

Affected products

• Xen Xen: version 4.4.0 only
