CVE-2026-27691
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.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
