Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.85.5

high Tenable Self-Hosted Container Security Plugin ID 451674

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: net: ip_tunnel: make sure to pull
 inner header in ip_tunnel_rcv() Apply the same fix than ones found in : 8d975c15c0cd ("ip6_tunnel: make
 sure to pull inner header in __ip6_tnl_rcv()") 1ca1ba465e55 ("geneve: make sure to pull inner header in
 geneve_rx()") We have to save skb->network_header in a temporary variable in order to be able to recompute
 the network_header pointer after a pskb_inet_may_pull() call. pskb_inet_may_pull() makes sure the needed
 headers are in skb->head. syzbot reported: BUG: KMSAN: uninit-value in __INET_ECN_decapsulate
