NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd:2.4/mod_md package and not the httpd:2.4/mod_md package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue.
