Summary
net: openvswitch: Fix Use-After-Free in ovs_ct_exit
Details

In the Linux kernel, the following vulnerability has been resolved:

net: openvswitch: Fix Use-After-Free in ovsctexit

Since kfreercu, which is called in the hlistforeachentryrcu traversal of ovsctlimitexit, is not part of the RCU read critical section, it is possible that the RCU grace period will pass during the traversal and the key will be free.

To prevent this, it should be changed to hlistforeachentrysafe.
