How to fix?

Upgrade Debian:12 libxml2 to version 2.9.14+dfsg-1.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.
