Description

CVE-2025-40149 affecting package kernel for versions less than 5.15.200.1-1

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.
