This basically means that fixes for most security vulnerabilities are not be able to be back-ported to LTS kernels but on the other side around stable releases contain all security fixes made so far.
In other words, use stable Kernels over LTS, whenever possible, assuming everything works for you and there are no specific circumstances such as working in an environment where you have no control over the Kernel - limited access etc.
I think I provided enough evidence to support this. I expected more as counter arguments that newer features in newer kernels can increase attack surface but this is all what there is on counter arguments.
Examples that are not in LTS are Lockdown LSM, STACKLEAK GCC plugin + Spectrev2.
Missing hardening features is very different than missing fixes. I would expect that LTS kernels don’t get new major features such as hardening changes even if they “improve security”.
The point is that what you call hardening features can help to address known vulnerabilities. This will increase security one way or another.
Now bring evidence that I am wrong, whops there is none.
Sure. I agree with “Prefer stable kernels because they have the latest security harderning”. I was just disagreeing with “most security vulnerabilities are not be able to be back-ported to LTS kernels”.
Haha. Good joke. Not worth responding to.
