CVE-2022-50071

The CVE-2022-50071 issue affects the Linux kernel’s MPTCP implementation. The vulnerability arises when socket creation fails due to a CGROUP_INET_SOCK_CREATE eBPF program, causing leakage of subflows because cleanup was not invoked in that code path. The fix moves subflow cleanup into the mptcp_...
