CVE-2026-86713

PX4 Autopilot through 1.17.0 contains a use-after-free vulnerability 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. Attackers can trigger this vulnerability by issuing the load mon stop command from any PXH or MAVLink shell, causing reads and writes through freed memory that corrupt heap objects and destabilize the flight stack.
