Stack Overflow Vulnerability in PX4 Autopilot for Drones

CVE-2026-32705

What is CVE-2026-32705?

The PX4 autopilot, a widely utilized flight control solution for drones, suffers from a vulnerability in its BST telemetry probe. Prior to version 1.17.0-rc2, this probe inaccurately writes a string terminator using an externally provided length, potentially leading to a stack overflow. If an attacker manipulates a BST device to report an oversized 'dev_name_len', they can crash the driver task or execute arbitrary code. Users are advised to update to version 1.17.0-rc2 to mitigate this risk. For additional details, refer to the official advisory.
