Title
mptcp: allow subflow rcv wnd to shrink
Summary
In the Linux kernel, the following vulnerability has been resolved: mptcp: allow subflow rcv wnd to shrink In MPTCP connection, the `window` field in the TCP header refers to the MPTCP-level rcv_nxt and it's right edge should not move backward. Such constraint is enforced at DSS option generation time. At the same time, the TCP stack ensures independently that the TCP-level rcv wnd right's edge does not move backward. That in turn causes artificial inflating of the MPTCP rcv window when the incoming data is acked at the TCP level and is OoO in the MPTCP sequence space (or lands in the backlog). As a consequence, the incoming traffic can exceed the receiver rcvbuf size even when the sender is not misbehaving. Prevent such scenario forcibly allowing the TCP subflow to shrink the TCP-level rcv wnd regardless of the current netns setting.

Application-level authentication is not required to reach the vulnerable TCP/MPTCP receive and ACK-generation code.\nUI:N - An attacker can target an MPTCP-enabled listener or service directly over the network. No victim user interaction is needed.\nS:U - The impact is within the same kernel/network stack security authority on the affected host. There is no VM escape, sandbox boundary crossing, or separate security scope involved.\nC:N - The bug causes receive-window over-advertisement and excessive receive-buffer consumption, not an out-of-bounds access, use-after-free, or information disclosure primitive. I found no path to reading kernel or application data.\nI:N - The affected logic corrupts flow-control accounting rather than attacker-controlled memory or persistent state. I found no arbitrary write, data modification, or control-flow hijack primitive.\nA:H - A remote peer can drive incoming MPTCP traffic beyond the intended receive-buffer limit, creating kernel socket-buffer memory pressure and denial of service against the host or service.
