CVE-2026-93590Network attack vectorHinoki check available

Service interruption via unchecked UHDR pixel allocation

Published Sep 18, 2026 · Updated Sep 18, 2026

Uncontrolled resource consumption in ImageMagick before 7.1.2-31 allows remote attackers to interrupt service via crafted UHDR images. The UHDR encoder allocates a buffer for every image pixel without applying the configured resource-policy check. Exploitation requires attacker-controlled input to reach UHDR encoding and can exhaust process memory, disrupting image-processing availability.
