Detailed vulnerability description
The vulnerability allows a remote #AU# to perform a denial of service (DoS) attack.
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.
