Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
sctp: close UDP tunnel sockets during netns teardown<br />
<br />
proc_sctp_do_udp_port() starts per-net SCTP UDP tunneling sockets when<br />
net.sctp.udp_port is set, and stops/restarts them when the sysctl value<br />
changes. The netns exit path does not stop these sockets, so a namespace<br />
can be torn down while its SCTP UDP tunnel sockets are still installed.<br />
<br />
Close the UDP tunnel sockets from sctp_ctrlsock_exit() after unregistering<br />
the per-net sysctl table. This prevents new sysctl writes from racing in<br />
while the sockets are being released, and closes the sockets before the<br />
control socket is destroyed.
