In affected versions if a consensus client sends a malformed consensus request to an orderer it may crash the orderer node.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
