Name of the Vulnerable Software and Affected Versions PX4 Autopilot versions 1.12.x through 1.15.x

Description The software contains a flaw in the protection mechanism within the 'Re-arm Grace Period' logic. The system incorrectly applies in-air emergency re-arm logic to ground scenarios. Switching to Manual mode and re-arming within 5 seconds of an automatic landing bypasses pre-flight safety checks, including the throttle threshold check. This allows for immediate high-thrust takeoff if the throttle stick is raised, potentially leading to loss of control.

Recommendations Versions 1.12.x through 1.15.x: Avoid switching to Manual mode and re-arming within 5 seconds after an automatic landing.
