CVE-2022-36862

Local service interruption via CJK heap overflow

Published Sep 9, 2022 · Updated Aug 3, 2024

A heap-based overflow in Samsung Mobile Devices before SMR Sep-2022 Release 1 allows local users to cause a memory access fault. HWR::EngineCJK::Impl::Construct() in libSDKRecognitionText.spensdk.samsung.so constructs CJK recognition state without proper boundary checks, overrunning a heap buffer. Low-privileged local access is required, and Samsung reports a memory access fault rather than code execution.
