Description
In the Linux kernel, the following vulnerability has been resolved:
mptcp: really cope with fastopen race
Fastopen and PM-trigger subflow shutdown can race, as reported by
syzkaller.
In my first attempt to close such race, I missed the fact that
the subflow status can change again before the subflow_state_change
callback is invoked.
Address the issue additionally copying with all the states directly
reachable from TCP_FIN_WAIT1.
Affected configurations
• linux linux kernel (>= 6.2 < 6.6.18)
• linux linux kernel (>= 6.7 < 6.7.6)
• linux linux kernel 6.8
