| Doc Text: |
A flaw was found in the Linux kernel’s TCP implementation in the function tcp_add_backlog(). When calculating the maximum acceptable backlog for TCP sockets, the sum of the receive buffer (sk_rcvbuf), the send buffer (sk_sndbuf), and a fixed constant may exceed the maximum value of a signed integer due to both buffer values being of type int. This can result in a signed integer overflow, potentially leading to incorrect backlog limits and unexpected TCP behavior under certain workloads.
