CVE-2022-49330

The CVE-2022-49330 issue affects the Linux kernel's MTU probing logic in net/ipv4/tcp_input.c. Specifically, tcp_mtu_probe() starts an MTU probe only when tcp_snd_cwnd(tp) is >= 11, but tcp_snd_cwnd(tp) can later be reduced before the probe completes, creating a scenario that could lead to a z...
