CVE-2026-27691Public exploit

Local tool crash via unchecked LUT dimensions

Published Feb 25, 2026 · Updated Feb 25, 2026

Signed integer overflow in iccFromCube in iccDEV 2.3.1.4 and earlier allows local users to crash the tool via crafted cube input. parse3DTable multiplies the signed m_sizeLut3D dimension by itself three times without first validating that the result fits, invoking undefined behavior before the size check. Exploitation requires local execution of iccFromCube against an attacker-controlled cube file and interrupts that process without demonstrated data disclosure or modification.
