Overview

CVE-2026-68336 is a known-severity vulnerability. It was published on August 10, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

bonding: fix devconf_all NULL dereference when IPv6 is disabled

When booting with the 'ipv6.disable=1' parameter, the devconf_all is

never initialized because inet6_init() exits before addrconf_init() is

called which initializes it. bond_send_validate(), however, will still

call bond_ns_send_all() even ipv6 is indeed disabled. It will lead to

NULL derefence of net->ipv6.devconf_all in ip6_pol_route().

BUG: kernel NULL pointer dereference, address: 000000000000000c
