How to fix?

There is no fixed version for Debian:12 jpeg-xl.

NVD Description

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

A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory.

This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the decoder to omit populating those areas.
