CVE Details
| Release Date: | 2026-08-10 | |
| Impact: | Low | What is this? |
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
[...]
Workqueue: bond0 bond_arp_monitor [bonding]
RIP: 0010:ip6_pol_route+0x69/0x480
