Description Alex 2023-02-26 16:34:04 UTC
A flaw in the Linux Kernel found. Fail if no bound addresses can be used for a given scope. A type confusion can happen in inet_diag_msg_sctpasoc_fill() in net/sctp/diag.c, which uses a type confused pointer to return information to userspace when issuing a list_entry() on asoc->base.bind_addr.address_list.next when the list is empty.
