CVE-2026-32724

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc1, a heap-use-after-free is detected in the MavlinkShell::available function. The issue is caused by a race condition between the MAVLink receiver thread which handles shell creation/destruction and the telemetry sender thre...

CVE-2026-32709

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, An unauthenticated path traversal vulnerability in the PX4 Autopilot MAVLink FTP implementation allows any MAVLink peer to read, write, create, delete, and rename arbitrary files on the flight controller filesystem withou...

CVE-2026-32705

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, the BST telemetry probe writes a string terminator using a device-provided length without bounds. A malicious BST device can report an oversized devnamelen, causing a stack overflow in the driver and crashing the task or...

CVE-2026-32707

PX4 autopilot is a flight control solution for drones. Prior to 1.17.0-rc2, tattucan contains an unbounded memcpy in its multi-frame assembly loop, allowing stack memory overwrite when crafted CAN frames are processed. In deployments where tattucan is enabled and running, a CAN-injection-capable...

CVE-2026-32708

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,...

PX4-Autopilot 安全漏洞

PX4-Autopilot is an open-source drone autopilot system developed by PX4. Versions of PX4-Autopilot prior to 1.17.0-rc2 contained security vulnerabilities. These vulnerabilities stemmed from Zenoh uORB subscribers not performing boundary checks when allocating variable-length arrays directly from...
