allocAckNak returns nullptr when the packet pool is exhausted, but allocErrorResponse passed the result straight to setReplyTo, which dereferences it. Reachable unauthenticated: an ADMIN_APP packet on a known-key channel takes the NOT_AUTHORIZED path, so a flood that empties the pool crashes the node. MemoryDynamic::alloc no longer aborting on failure made this reachable on PSRAM, STM32WL and Portduino targets. Callers already treat a null reply as no response. Same fix for the two RemoteHardwareModule sites.
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
