CVE-2026-24407Public exploitNetwork attack vector

Processing interruption via out-of-range operator signature

Published Jan 24, 2026 · Updated Jan 24, 2026

Undefined behavior in icSigCalcOp in iccDEV 2.3.1.1 and earlier allows remote attackers to interrupt processing via malformed ICC data. The parser loads an attacker-controlled 32-bit operator signature into the icSigCalcOp enum even when the value falls outside its declared range. User interaction is required to process the crafted profile; the demonstrated result is a UBSan failure and aborted round trip, while downstream memory corruption or code execution depends on the consuming native library.
