Frequently Asked Questions

1

What conditions are required to trigger the issue?

A generic netlink controller policy dump must remain pending across multiple socket buffers, and the target generic netlink family must then be unregistered with its module unloaded before the dump advances. The subsequent dump processing can dereference policy memory belonging to the unloaded module.

2

Which systems are exposed?

Systems are exposed when they use generic netlink policy dumps for a target family whose operation and policy tables are provided by an unloadable module. The provided information does not identify specific distributions, kernel versions, or default configurations.

3

What is the relevant mitigation if an update cannot be applied immediately?

Avoid unregistering and unloading a target generic netlink family module while a controller policy dump for that family may still be pending. The resolved change prevents the condition by holding a reference to the target family's module for the lifetime of the dump context.
