NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-usb package and not the kernel-uek-debug-modules-usb package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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

tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().

get_netdev_for_sock() is called during setsockopt(), so not under RCU.

Using sk_dst_get(sk)->dev could trigger UAF.

Let's use __sk_dst_get() and dst_dev_rcu().

Note that the only ->ndo_sk_get_lower_dev() user is bond_sk_get_lower_dev(), which uses RCU.
