CVE-2026-31793Public exploit

Application crash via unchecked operation count

Published Mar 10, 2026 · Updated Mar 10, 2026

Out-of-bounds read in iccDEV before 2.3.1.5 allows local users to crash profile-processing applications via a crafted ICC profile. CIccCalculatorFunc::ApplySequence calculates a sequence end by adding an untrusted operation count before checking for overflow, allowing iteration to reach an invalid pointer. A user or application must process the profile; the resulting segmentation fault terminates the affected process without reported data disclosure or modification.
