The Alpine security team deemed this advisory irrelevant for Alpine:3.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Alpine.
An issue was discovered in Xen through 4.11.x allowing 64-bit PV guest OS users to cause a denial of service (host OS crash) because #GP[0] can occur after a non-canonical address is passed to the TLB flushing code. NOTE: this issue exists because of an incorrect CVE-2017-5754 (aka Meltdown) mitigation.
