Red Hat advises not to open untrusted Radiance HDR files (.hdr, .pic) in applications that use the GEGL library. There is no indication that a patch is currently available; therefore, avoiding untrusted files is the primary mitigation. Monitor the Red Hat advisory for updates regarding fixes.
Description
CVE-2026-103641 is a vulnerability in the GEGL library used by Red Hat Enterprise Linux 10. The Radiance HDR loader in GEGL reads beyond the end of a memory-mapped image when an uncompressed scanline is shorter than the width declared in the file header. This can cause applications using the loader to crash when opening specially crafted HDR files. The flaw requires local user interaction to exploit and results in denial of service by application termination without allowing code execution or data modification.
