In affected versions a global buffer overflow vulnerability exists in the CrsfParser_TryParseCrsfPacket function in /src/drivers/rc/crsf_rc/CrsfParser.cpp:298 due to the invalid size check. A malicious user may create an RC packet remotely and that packet goes into the device where the _rcs_buf reads.
