CVE-2022-36844

Memory-access fault via missing boundary check

Published Sep 9, 2022 · Updated Aug 3, 2024

Heap overflow in Samsung Mobile Devices Q(10), R(11), and S(12) before SMR Sep-2022 Release 1 allows local users to cause a memory-access fault. The HWR::EngJudgeModel::Construct() function in libSDKRecognitionText.spensdk.samsung.so lacks the boundary check needed to prevent a heap buffer overwrite during model construction. Local low-privilege access is required, and the documented consequence is a memory-access fault in the affected library.
