CVE-2026-61864

Memory leak via failed log colorspace conversion

Published Jul 15, 2026 · Updated Jul 15, 2026

Memory leak in ImageMagick before 7.1.2-26 and before 6.9.13-51 allows local users to consume memory via failed log colorspace conversion. TransformsRGBImage in MagickCore/colorspace.c returns after SyncImage or SetImageStorageClass fails without relinquishing its allocated logmap buffer. Reachability requires a PseudoClass image and failure during conversion to LogColorspace; repeated failures incrementally reduce available memory.
