What is CVE-2025-12474?

A vulnerability in the libjxl decoder allows specially-crafted files to exploit memory exposure issues, enabling potential data leakage. The flaw arises from the decoder referencing uninitialized memory that has been allocated, typically caused by incorrect optimizations. This can lead to the decoder omitting necessary data population for areas outside the expected image bounds, raising significant security concerns for applications utilizing this library.
