Description

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.

Affected configurations

• linux linux kernel (>= 4.18 < 5.15.199) • linux linux kernel (>= 5.16 < 6.1.161) • linux linux kernel (>= 6.2 < 6.6.121) • linux linux kernel (>= 6.7 < 6.12.66) • linux linux kernel (>= 6.13 < 6.17.3)
