How to fix?

There is no fixed version for xen.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.
