Technical details

A use-after-free vulnerability exists in the load_mon module's stop path where exit_and_cleanup() deletes the LoadMon object and frees the performance counter before perf_end() attempts to access it. An attacker with access to any PXH or MAVLink shell can trigger this by issuing the load_mon stop command, causing reads and writes through freed memory that corrupt heap objects and destabilize the flight stack. The vulnerability affects PX4 Autopilot through version 1.17.0. Patch availability is not indicated in the advisory.
