How to fix?

Upgrade Alpine:3.11 bind to version 9.16.4-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine. See How to fix? for Alpine:3.11 relevant fixed versions and status.

An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients.
