Alta Video —1408: BusyBox ash shell had a stack overflow vulnerability

Release Date

18th of March 2026.

Overview

A stack overflow vulnerability was discovered in ash shell in BusyBox versions prior to 1.35. The vulnerability could be triggered via a command, potentially leading to arbitrary code execution. Although the vulnerability was rated as critical, exploitation on certain camera platforms was difficult due to the exposure of the ash shell being limited to the camera's custom shell, requiring local network access, and having argument validation.
