I believe comma is more widespread per country

it looks like you might be right... I'm surprised to learn that https://en.wikipedia.org/wiki/Decimal_separator#Conventions_worldwide lists 83 countries who use comma as decimal separator, and only 59 who use dot (and presumably the thousands separator is usually the opposite of the decimal separator). However there are enough countries which aren't on either list that it isn't entirely clear from that page which convention is actually used in more countries.

Also, it's much more complicated than the . vs , binary... among other oddities:

• Historically, in Germany and Austria, thousands separators were occasionally denoted by alternating uses of commas and points, e.g. "1.234,567.890,12" (or "1.234,567.890·12" in Austria-Hungary and Austria prior to 1938) for "eine Milliarde 234 Millionen ...", but this is not seen today and contemporary German readers would require an explanation to understand it.
• In Switzerland, there are two styles. Currency values use an apostrophe (') as a thousands separator along with a dot (.) as the decimal separator, like "1'234'567.89". For other values, the SI-style "1 234 567,89" is used, with a comma (,) as the decimal separator. The apostrophe is also the most common thousands separator for non-currency values, like "1'234'567,89".

Yes, hence why you would have to check the CVSS of all of those.

But still listing year’s old vulnerabilities that got fixed long ago because they are still supporting ancient stuff like 5.10LTS is Debian-specific.

The advisory this meme is about only relates to the 6.12 kernel in Debian 13 "trixie" (Debian's current stable release), and 1,295 of these 1,313 CVEs are from 2026.

Linux 6.12 is the SLTS ("super long-term support") release from 2024, so the Linux Foundation's Civil Infrastructure Platform plans to continue backporting security fixes to it until 2035.

Debian stopped supporting Debian 11 "bullseye" (the one with a 5.10 kernel) in August, but that kernel is also an SLTS which CIP plans to support until 2031.

So, no, continuing support for these kernels is not something Debian-specific.

Here are the versions of linux-image-amd64 in Debian currently:
