#93991 — Informations about release date of Debian kernel

[Multipart message — attachments visible in raw view] — view raw

Hello,

As a security auditer, I would like to identify when a specific kernel version has been released.
I tried to found the information on the Internet, but I fail to find what I am looking for...

Do you maybe know where I can find that ?

For example, it isn't specified on the web site of the package https://packages.debian.org/trixie/kernel/linux-image-6.12.94+deb13-amd64

Thank you in advance.

Best Regards,
Florian LAURENT

What exactly do you mean by "released"? Do you mean the upstream release 
on kernel.org, or the upload of a Debian package containing said kernel 
to unstable, or the release of the Debian stable distribution contianing 
said kernel?

And with that, we have not yet started to look at backports, stable 
point releases, security and stable updates, ...

You need to be familiar with how Debian works to make real use of that 
information. What is the object of your question?

Greetings
Marc

And what for? What is the actual aim here?

All of this information is readily available online.

IMHO it is not even hard to find. I would claim that a security auditor 
would be able to find resources such as¹:

- upstream: https://kernel.org or via RSS: http://kernel.org/kdist/rss.xml

- Debian packaged kernels if package name is known:
https://tracker.debian.org

- In addition to that mailing lists like this one or debian-devel-changes, 
debian-backport-changes or search for "linux security update" in debian-
security-announce mailing list just to name a few.

Or even the changelog of an installed kernel package.

Of course this list is not complete.

In addition to that there is debsecan and apticron.

Depending on which source you use there might be some inaccuracy, cause 
for example a date in package changelog does not reflect when a new kernel 
packages actually is available on a certain mirror. And when it is, you 
still do not know when the package was installed on a certain system, 
unless you look there.

Not all of the above is specific to just kernels. However the kernel is by 
no means the only relevant component when it is about assessing the 
security status of a Debian system.



[1] Using the search engine of your choice. I bet none of the resources 
mentioned above are really difficult to find if willing to invest some 
time.

Best,
