Assigned:2014-08-12
Published:2014-08-12
Updated:2018-10-30
Summary: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.
