Summary
PX4 autopilot has a global buffer overflow in crsf_rc via oversized variable-length known packet
Details

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, The crsfrc parser accepts an oversized variable-length known packet and copies it into a fixed 64-byte global buffer without a bounds check. In deployments where crsfrc is enabled on a CRSF serial port, an adjacent/raw-serial attacker can trigger memory corruption and crash PX4. This vulnerability is fixed in 1.17.0-rc2.
