Lifecycle Timeline
3Description
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.
Analysis
PX4 autopilot versions prior to 1.17.0-rc2 contain an unbounded memcpy vulnerability in the tattu_can module that allows stack memory corruption when processing specially crafted CAN frames. An attacker with CAN bus injection capability can trigger denial of service or memory corruption in drone systems where tattu_can is enabled, potentially compromising flight safety and system stability.
