CVE-2025-12474: Libjxl Project Libjxl

Medium severity, CVSS 4.4. 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.

Affected products

• Libjxl Project Libjxl: from 0.7.0, up to and including 0.11.1
