Description
The issue is related to a use-after-free error in the

For Linux kernel versions prior to 5.3.9, update to version 5.3.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the
aa audit rule init() function until a patch is available. Found an issue in the description? Have something to add? Feel free to write us 👾
