My understanding is that “upstream sources” refers to the sources provided by kernel.org to the distributions. The kernel version/release numbers remain unchanged when the distribution—i.e. Manjaro—delivers them.
To stick with my example:
In https://lore.kernel.org/linux-cve-announce/2026021300-CVE-2026-23111-9762@gregkh/ it states: "
The official CVE entry at
https://cve.org/CVERecord/?id=CVE-2026-23111
will be updated if fixes are backported, please check that for the most
up to date information about this issue."
Among other ranges, the range unaffected from 6.18.10 through 6.18.* is listed there. My computer shows “6.18.33-1-MANJARO” when running uname -r. Do I understand correctly that the kernel I am using falls within this range and is therefore “unaffected”?
