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

{
    "lastseen": "",
    "description": "A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory.\n\nThis 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.",
