CVE-2026-34533
Description
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) in CIccCalculatorFunc::ApplySequence() due to invalid enum values being loaded for icChannelFuncSignature. The issue is observable under UBSan as a “load of value … not a valid value for type icChannelFuncSignature”, indicating a type/enum value confusion scenario during ICC profile processing. This issue has been patched in version 2.3.1.6.
