On platforms where these pools are heap-backed (MemoryDynamic - used whenever there isn't enough static RAM for a fixed pool, e.g. ARCH_STM32WL or BOARD_HAS_PSRAM), allocCopy()/allocZeroed() return nullptr on allocation failure and already log a warning, but most callers dereferenced the result unconditionally. Under real heap pressure this reliably produced a HardFault - reproduced on STM32WL hardware under sustained mesh traffic, including the RX entry point (RadioLibInterface::handleReceiveInterrupt) where every received packet is allocated. Adds null checks at all call sites that were missing one, mirroring the guard pattern already used correctly elsewhere in the same files (e.g. RadioInterface.cpp's sendErrorNotification). On allocation failure, callers now skip the send/retransmission/notification and log nothing further (the allocator already did) rather than crash.

Meshtastic Firmware
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.
