CVE-2026-103641 PUBLISHED

Gegl: gegl04: gegl: out-of-bounds read in the radiance hdr uncompressed scanline decoder

Assigner: redhat
Reserved: 01.10.2026 Published: 01.10.2026 Updated: 01.10.2026

A flaw was found in GEGL. The Radiance HDR loader reads past the end of a memory-mapped image when an uncompressed scanline is shorter than the width declared in the file header. Opening a crafted HDR file crashes the application that uses the loader.
