CVE-2026-32707: Dronecode PX4 Drone Autopilot

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, tattu_can contains an unbounded memcpy in its multi-frame assembly loop, allowing stack memory overwrite when crafted CAN frames are processed. In deployments where tattu_can is enabled and running, a CAN-injection-capable attacker can trigger a crash (DoS) and memory corruption. This vulnerability is fixed in 1.17.0-rc2.

Affected products

• Dronecode PX4 Drone Autopilot: before 1.17.0 (fixed in 1.17.0); version 1.17.0 only
