Lifecycle Timeline
3Description
PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, The crsf_rc 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 crsf_rc 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.
Analysis
Buffer overflow vulnerability in PX4 autopilot drone firmware versions before 1.17.0-rc2 that allows adjacent network attackers to crash the system by sending oversized CRSF packets. The vulnerability requires the CRSF receiver protocol to be enabled on a serial port and can cause memory corruption leading to denial of service. …

Remediation
Within 24 hours: Inventory all PX4 autopilot systems in operation and identify which have CRSF receiver protocol enabled on serial ports. Within 7 days: Isolate affected drone systems from untrusted networks or disable CRSF receiver protocol if operationally feasible; document any systems that cannot be immediately remediated. …
