I want to check if the version of the debian package installed in my ubuntu server is vulnerable or not based on the information provide by Ubuntu Security Notices for a particular CVE.

For example, the version of kernel running in my server is 5.4.0-80-generic and the TIPC vulnerability affecting the linux kernel is provided on https://ubuntu.com/security/CVE-2021-43267. I am running Ubuntu 20.04 and for the linux kernel (the first entry) the status is Not vulnerable (5.4.0-9.12).

So any clue if I am vulnerable or not ?
