CVE-2026-24412Public exploitNetwork attack vector

Code execution via mismatched MCurves dimension count

Published Jan 24, 2026 · Updated Jan 24, 2026

Heap-based buffer overflow in iccDEV before 2.3.1.2 allows remote attackers to execute code through crafted ICC profile XML. icMBBFromXml allocates the MCurves array for one matrix dimension but passes the opposite nIn or nOut count to icCurvesFromXml, which writes pointers beyond that allocation. Exploitation requires a user or consuming application to process attacker-controlled profile XML and results in a crash or, in affected native-processing contexts, arbitrary code execution.
