Description
In the Linux kernel, the following vulnerability has been resolved:
sctp: Prevent TOCTOU out-of-bounds write
For the following path not holding the sock lock,

make sure not to exceed bounds in case the address list has grown
between buffer allocation (time-of-check) and write (time-of-use).
