Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mptcp: cope racing subflow creation in mptcp_rcv_space_adjust<br /> <br /> Additional active subflows - i.e. created by the in kernel path<br /> manager - are included into the subflow list before starting the<br /> 3whs.<br /> <br /> A racing recvmsg() spooling data received on an already established<br /> subflow would unconditionally call tcp_cleanup_rbuf() on all the<br /> current subflows, potentially hitting a divide by zero error on<br /> the newly created ones.<br /> <br /> Explicitly check that the subflow is in a suitable state before<br /> invoking tcp_cleanup_rbuf().
