CVE-2022-36845

Memory access fault via missing boundary check

Published Sep 9, 2022 · Updated Aug 3, 2024

Heap-based buffer overflow in Samsung Mobile Devices Q(10), R(11), and S(12) allows local users to cause a memory access fault. The MHW_RECOG_LIB_INFO function in libSDKRecognitionText.spensdk.samsung.so omits a proper boundary check, permitting a heap buffer overflow. Exploitation requires local low-privileged access and can interrupt the recognition component while causing limited integrity impact.
