CVE-2025-12474

2.3 lowEPSS 0.1%

Low (2.3) in libjxl project libjxl. EPSS 0.1% chance of exploitation in the next 30 days.

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.
