CVE-2024-31142  (opens in a new tab)

How to fix?

Upgrade Alpine:3.16 xen to version 4.16.6-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Alpine. See How to fix? for Alpine:3.16 relevant fixed versions and status.

Because of a logical error in XSA-407 (Branch Type Confusion), the mitigation is not applied properly when it is intended to be used. XSA-434 (Speculative Return Stack Overflow) uses the same infrastructure, so is equally impacted.
