CVE-2025-12474 libjxl: Uninitialized memory read in decoder due to incorrect optimization in patch handling

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...

CVE-2025-12474

The CVE describes a vulnerability in libjxl where a specially crafted file can cause the decoder to read pixel data from uninitialized memory, due to referencing an outside-image-bound area in later patches and an optimization that omits populating those areas. Several connected advisories confir...
