Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: Fix Use-After-Free in ovs_ct_exit
Since kfree_rcu, which is called in the hlist_for_each_entry_rcu traversal
of ovs_ct_limit_exit, 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 hlist_for_each_entry_safe.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: openvswitch: Fix Use-After-Free en ovs_ct_exit Dado que kfree_rcu, que se llama en el recorrido hlist_for_each_entry_rcu de ovs_ct_limit_exit, no forma parte de la sección crítica de lectura de RCU, es posible que el período de gracia de RCU pasará durante el recorrido y la clave quedará libre. Para evitar esto, se debe cambiar a hlist_for_each_entry_safe.
