CVE-2026-34552Public exploit

Local process crash via null LUT pointer

Published Mar 31, 2026 · Updated Mar 31, 2026

Null-pointer dereference in iccDEV before 2.3.1.6 allows local users to crash ICC profile-processing tools via a crafted profile. NDInterp cases in IccTagLut.cpp leave a CIccApplyCLUT pointer uninitialized, then access its members while processing the profile. Processing the supplied profile with iccRoundTrip reaches the faulty LUT application path; the documented consequence is a process crash, with no confidentiality or integrity impact.
