CVE-2021-47590

CVE-2021-47590 affects the Linux kernel MPTCP path. The deadlock occurs when __mptcp_push_pending() calls mptcp_flush_join_list() while holding the subflow socket lock, enabling __mptcp_sockopt_sync() to lock the subflow socket. The fix uses __mptcp_flush_join_list() (not plain mptcp_flush_join_l...
