In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: Fix the dead loop of MPLS parse
The unexpected MPLS packet may not end with the bottom label stack. When there are many stacks, The label count value has wrapped around. A dead loop occurs, soft lockup/CPU stuck finally.
