ImageMagick <7.1.2-15 & <6.9.13-40: NULL Deref in ReadSFWImage
CVE-2026-25795 Published on February 24, 2026
ImageMagick has NULL pointer dereference in ReadSFWImage after DestroyImageInfo (sfw.c)
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in `ReadSFWImage()` (`coders/sfw.c`), when temporary file creation fails, `read_info` is destroyed before its `filename` member is accessed, causing a NULL pointer dereference and crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
