Frequently Asked Questions

1

Which Ubuntu kernel package families are listed as affected?

The listed software includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, and their FIPS variants: linux-fips, linux-aws-fips, linux-azure-fips, and linux-gcp-fips.

2

What level of access would an attacker need?

The supplied vector indicates local access with low privileges is required. No user interaction is required, but exploitation also has an additional attack requirement (AT:P).

3

What is the expected security impact?

The vector indicates high availability impact, with no confidentiality or integrity impact. The reported failure is a kernel NULL-pointer dereference that can produce an Oops during IPv6 route-device handling.

4

How can an administrator recognize a possible occurrence?

Look for kernel crash or Oops records referencing rt6_uncached_list_flush_dev or rt6_disable_ip, including a KASAN null-ptr-deref report. The supplied example occurred in net/ipv6/route.c while disabling IPv6 routing state.
