PX4 Autopilot Logic Flaws

PX4 Autopilot versions 1.12.x through 1.15.x contain a logic flaw in the mode switching mechanism. [CVSS 8.1 HIGH]

PX4 Autopilot versions 1.12.x through 1.15.x can be forced into an unsafe re-arm state when pilots switch to Manual mode and re-arm within 5 seconds of landing, bypassing critical pre-flight safety checks and throttle validation. This allows attackers or malicious pilots to trigger immediate high-thrust takeoff, resulting in loss of aircraft control. Public exploit code exists for this vulnerability and no patch is currently available.
