Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
macvlan: fix possible UAF in macvlan_forward_source()<br />
<br />
Add RCU protection on (struct macvlan_source_entry)->vlan.<br />
<br />
Whenever macvlan_hash_del_source() is called, we must clear<br />
entry->vlan pointer before RCU grace period starts.<br />
<br />
This allows macvlan_forward_source() to skip over<br />
entries queued for freeing.<br />
<br />
Note that macvlan_dev are already RCU protected, as they<br />
are embedded in a standard netdev (netdev_priv(ndev)).<br />
