Vulnerability from github – Published: 2026-02-11 18:31 – Updated: 2026-02-11 18:31

Details

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.

Severity ?

2.3 (Low)
