Technical details
A stack-based buffer overflow exists in Svc::TlmPacketizer's TlmRecv_handler, which copies telemetry serialized values into fixed-slot storage without bounds checking. When a channel value's serialized size exceeds the allocated slot size, the copy operation overwrites adjacent channel fields, corrupting packetized telemetry. This requires network access to send malformed telemetry packets to the affected component.
