What is CVE-2026-32707?

CVE-2026-32707 is a medium-severity memory corruption vulnerability in PX4-Autopilot, published on 13 Mar 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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.

Weakness: CWE-121
