In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: treat all calls not a bcall when bc_serv is NULL
When a rdma server returns a fault format reply, nfs v3 client may treats it as a bcall when bc service is not exist.
The debug message at rpcrdmabcreceive_call are,
[56579.837169] RPC: rpcrdmabcreceivecall: callback XID 00000001, length=20 [56579.837174] RPC: rpcrdmabcreceivecall: 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 04
After that, rpcrdmabcreceive_call will meets NULL pointer as,
