In the Linux kernel, the following vulnerability has been resolved: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL The SCTP_SENDALL path in sctp_sendmsg() iterates ep->asocs with list_for_each_entry_safe(), which caches the next entry in @tmp before the loop body runs. The body calls sctp_sendmsg_to_asoc(), which may drop the socket lock inside sctp_wait_for_sndbuf(). While the lock is dropped, another thread can SCTP_SOCKOPT_PEELOFF the association cached in @tmp, migrating it to a new endpoint via sctp_sock_migrate() (list_del_init() + list_add_tail() to newep->...

조치방안
제3자 참조와 수정 버전 값(5.10.258, 5.15.209, 6.1.175, 6.6.140, 6.12.90, 6.18.32, 7.0.9)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support 5.10.258, 5.15.209, 6.1.175, 6.6.140, 6.12.90, 6.18.32, 7.0.9 기준을 충족하는지 확인합니다. 이어서 경쟁 조건·TOCTOU 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
