AI-suggested
Organizations should immediately upgrade PX4-Autopilot to version 1.17.0-rc2 or later, where the vulnerability is fixed. Until upgrades are applied, restrict access to the Zenoh communication interface to trusted and authenticated entities only, minimizing exposure to untrusted local users or devices. Implement network segmentation and strict access controls to prevent unauthorized local access to drone control systems. Conduct thorough code reviews and fuzz testing on any custom extensions or integrations with the Zenoh uORB subscriber to detect similar unsafe memory operations. Employ runtime protections such as stack canaries, address space layout randomization (ASLR), and control flow integrity (CFI) where supported by the platform to mitigate exploitation impact. Monitor drone system logs for unusual crashes or communication anomalies indicative of attempted exploitation. Finally, maintain an incident response plan tailored to drone operational environments to quickly address potential compromises.
Description
PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, the Zenoh uORB subscriber allocates a stack VLA directly from the incoming payload length without bounds. A remote Zenoh publisher can send an oversized fragmented message to force an unbounded stack allocation and copy, causing a stack overflow and crash of the Zenoh bridge task. This vulnerability is fixed in 1.17.0-rc2.
