      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: prevent peer transport count overflow\n\nsctp_assoc_add_peer() increments the association's 16-bit transport_count\nfor every new unique peer. Adding the 65,536th transport wraps the count to\nzero.\n\nSCTP sock_diag uses transport_count to reserve the INET_DIAG_PEERS payload,\nthen copies one sockaddr_storage for every entry in transport_addr_list.\nAfter the wrap, a diagnostic dump reserves an empty payload and writes\n8 MiB of peer addresses past the skb tail.\n\nReject a new unique peer when transport_count has reached U16_MAX. Perform\nthe check after the existing-peer lookup so a duplicate address continues\nto return its existing transport at the limit.",
