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

medium Tenable Cloud Security Plugin ID 450649

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: make sure to pull inner header
 in geneve_rx() syzbot triggered a bug in geneve_rx() [1] Issue is similar to the one I fixed in commit
 8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()") 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.
