CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2024-26708
Medium (5.5) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
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.
