CVE-2026-68322 is a known-severity vulnerability. It was published on August 10, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
rds: Fix inet6_addr_lst NULL dereference when IPv6 is disabled
When booting with the 'ipv6.disable=1' parameter, inet6_addr_lst
is never initialized because inet6_init() exits before addrconf_init()
is called to initialize it. An attempt to bind an RDS socket to
an ipv6 address results in a crash in __ipv6_chk_addr_and_flags()
KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]
RIP: 0010:__ipv6_chk_addr_and_flags+0x1df/0x7e0
