Stack corruption via unbounded locale filename copy
Published Sep 26, 2022 · Updated May 22, 2025
Stack buffer overflow in mIPC camera firmware 5.3.1.2003161406 allows remote authenticated users to corrupt process memory via locale input. The locale-setting path passes an attacker-controlled locale-file value to unbounded strcpy, which writes beyond the destination stack buffer. The overflow exposes the camera process to arbitrary code execution or a crash after low-privileged network access reaches the locale-setting operation.
