CVE-2026-32743: CWE-121: Stack-based Buffer Overflow in PX4 PX4-AutopilotCVE-2026-32743 0 CVE-2026-32743 is a stack-based buffer overflow vulnerability in PX4-Autopilot versions 1.17.0-rc2 and earlier. The flaw exists in the MavlinkLogHandler component, where a fixed 60-byte buffer is overflowed due to unbounded sscanf parsing of file paths. An attacker with MAVLink link access can exploit this by creating deeply nested directories via MAVLink FTP and then requesting the log list, causing the flight controller's MAVLink task to crash. This results in denial of service by loss of telemetry and command capabilities. The vulnerability does not impact confidentiality or integrity but severely affects availability. No authentication or user interaction is required to trigger the issue. The vulnerability has a CVSS score of 6.5 (medium severity) and has been fixed in a recent commit.
