Out-of-bounds reads via unchecked packet access
Published Oct 13, 2026 · Updated Oct 13, 2026
Out-of-bounds packet reads in Siemens Desigo and Capital Embedded AR Classic allow remote attackers to read beyond packet buffers. Packet processing accesses data without first validating input bounds; the supplied record does not identify the protocol, function, or malformed field, and no matching public advisory was retrieved. Exploitation requires unauthenticated network access, but disclosure to attackers, crashes, and code execution are not established.
