Code execution via unchecked HTTP request copy
Published Mar 26, 2025 · Updated Mar 27, 2025
Stack-based buffer overflow in Silicon Labs Gecko OS 1.0.46 allows network-adjacent attackers to execute code via crafted HTTP requests. The HTTP request handler copies user-supplied data into a stack buffer without first validating its length. No authentication is required, and successful exploitation executes code in the device context.
