  "details": "In the Linux kernel, the following vulnerability has been resolved:  selinux: avoid sk_socket dereference in selinux_sctp_bind_connect()  selinux_sctp_bind_connect() dereferences sk-\u003esk_socket to pass a struct socket * to selinux_socket_bind() and selinux_socket_connect_helper().  However, when the hook is invoked from the ASCONF softirq path (sctp_process_asconf), there is no file reference guaranteeing that sk-\u003esk_socket is non-NULL.  The setsockopt callers (bindx, connectx, set_primary, sendmsg connect) hold a file reference and are not affected.  Both selinux_socket_bind() and selinux_socket_connect_helper() immediately resolve sock-\u003esk, never using the struct socket * for anything else.  Refactor the inner logic into helpers that take a struct sock * directly so that selinux_sctp_bind_connect() never needs to touch sk-\u003esk_socket at all.",
