CVE-2026-24411Public exploitNetwork attack vector

Service interruption via invalid segmented-curve downcast

Published Jan 24, 2026 · Updated Jan 24, 2026

Type confusion in iccDEV before 2.3.1.2 allows remote attackers to interrupt profile processing or corrupt data via a crafted ICC profile. CIccTagXmlSegmentedCurve::ToXml type-puns a CIccSegmentedCurve pointer as CIccSegmentedCurveXml and invokes a member on an object of the wrong dynamic type. Exploitation requires a user or application to process attacker-supplied profile data; the demonstrated result is undefined behavior, while downstream native consumers face data corruption or service interruption.
