Hi,

The following vulnerability was published for jpeg-xl.

CVE-2025-12474[0]:
| 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.
