Alpine: xen: security update to 4.16.6-r2

high Tenable Cloud Security Plugin ID 408522

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In x86's APIC (Advanced Programmable Interrupt Controller) architecture, error conditions are reported in
 a status register. Furthermore, the OS can opt to receive an interrupt when a new error occurs. It is
 possible to configure the error interrupt with an illegal vector, which generates an error when an error
 interrupt is raised. This case causes Xen to recurse through vlapic_error(). The recursion itself is
 bounded; errors accumulate in the the status register and only generate an interrupt when a new status bit
 becomes set. However, the lock protecting this state in Xen will try to be taken recursively, and
 deadlock. (CVE-2024-45817)
