Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The compatibility mode hypercall argument translation in Xen 3.3.x through 4.4.x, when running on a 64-bit hypervisor, allows local 32-bit HVM guests to cause a denial of service (host crash) via vectors involving altering the high halves of registers while in 64-bit mode.
Remediation
