CVE-2026-27691 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. iccDEV provides a set of libraries and tools for working with ICC color management profiles. In versions up to and including 2.3.1.4, signed integer overflow in iccFromCube.cpp during multiplication triggers undefined behavior, potentially causing crashes or incorrect ICC profile generation when processing crafted/large cube inputs. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
