How to fix?

Upgrade Alpine:3.20 apache2 to version 2.4.46-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2 package and not the apache2 package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
