CVE-2026-32743 affects PX4 Autopilot versions 1.17.0-rc2 and earlier. The vulnerability is a stack-based buffer overflow in the MavlinkLogHandler logic that processes log list entries. Specifically, the LogEntry.filepath buffer is 60 bytes, but sscanf parses file paths from the log list file without a width specifier, allowing an overlong path to overflow the stack buffer. According to the provided description, an attacker with MAVLink link access can prepare the condition by creating deeply nested directories via MAVLink FTP and then trigger the vulnerable code path by issuing a MAVLink log request for the log list.
