Loading vulnerability…
CVE-2023-1074 is a flaw in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation's handling of associations for which no bound address is usable in a requested scope. In the SCTP diagnostic path, inet_diag_msg_sctpasoc_fill() can invoke list_entry() on the next pointer of an empty bound-address list, producing a type-confused pointer while returning association information to userspace. The condition is associated with a memory leak that can be repeatedly triggered to consume kernel resources.
