CVE-2022-36863

Local service interruption via missing heap boundary check

Published Sep 9, 2022 · Updated Aug 3, 2024

Heap overflow in Samsung Mobile Devices running Q(10), R(11), or S(12) allows local users to trigger a memory-access fault. The GetCorrectDbLanguageTypeEsPKc function in libSDKRecognitionText.spensdk.samsung.so lacks a boundary check before writing into heap memory. Reachability requires local low-privileged access, and the reported consequence is limited to a memory-access fault in the affected component.
