Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2025-40149)
