NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-core package and not the kernel-uek-debug-core package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

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

ndisc: extend RCU protection in ndisc_send_skb()

ndisc_send_skb() can be called without RTNL or RCU held.

Acquire rcu_read_lock() earlier, so that we can use dev_net_rcu() and avoid a potential UAF.
