CVE-2022-50243 is a use-after-free vulnerability in the Linux kernel SCTP authentication-key handling. If sctp_auth_asoc_init_active_key() returns an error, the association active key is not updated, but key-management logic can free the previous shared key while the association still references it as its active key. A subsequent SCTP packet send dereferences the freed key through SCTP authentication handling. The fix prevents replacement of the shared key when active-key initialization fails and restores the previous active-key identifier when the corresponding active-key operation fails.
