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: geneve: fix header validation in
 geneve[6]_xmit_skb syzbot is able to trigger an uninit-value in geneve_xmit() [1] Problem : While most ip
 tunnel helpers (like ip_tunnel_get_dsfield()) uses skb_protocol(skb, true), pskb_inet_may_pull() is only
 using skb->protocol. If anything else than ETH_P_IPV6 or ETH_P_IP is found in skb->protocol,
 pskb_inet_may_pull() does nothing at all. If a vlan tag was provided by the caller (af_packet in the
 syzbot case), the network header might not point to the correct location, and skb linear part could be
 smaller than expected. Add skb_vlan_inet_prepare() to perform a complete mac validation. Use this in
 geneve for the moment, I suspect we need to adopt this more broadly. v4 - Jakub reported v3 broke
 l2_tos_ttl_inherit.sh selftest - Only call __vlan_get_protocol() for vlan types. v2,v3 - Addressed Sabrina
