In the Linux kernel, the following vulnerability has been resolved:
mptcp: Correctly set DATA_FIN timeout when number of retransmits is large
Syzkaller with UBSAN uncovered a scenario where a large number of
DATA_FIN retransmits caused a shift-out-of-bounds in the DATA_FIN
timeout calculation:
This change limits the maximum timeout by limiting the size of the
shift, which keeps all intermediate values in-bounds.
