CVE-2026-6840

Model-loading crash via unchecked operator code

Published Apr 22, 2026 · Updated Apr 22, 2026

Improper array-index validation in Samsung ONE 1.30.0 allows local users to crash model loading through a crafted neural-network model. The model loader uses an operator code for an out-of-range lookup without first validating that the code falls within the operator table bounds. The user must open or otherwise load the crafted model; the published assessment limits the resulting impact to availability.
