/area release-eng

/kind documentation

Similar to #105058. It seems that the CVE information was not added automatically for the 1.22 release notes.

Does this PR introduce a user-facing change?

NONE

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

Hi @ialidzhikov. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I simply copied the section from another CHANGELOG. So if we decide to apply the suggested changes, then I think the proper way would be to apply them to all similar sections in the corresponding CHANGELOG files. Do you insist on your suggestions to be applied for all CHANGELOG files or do you rather vote to keep it as it is?

Let's keep it as-is. I didn't realize that this was a problem for all of the sections.
Opened kubernetes/release#2284 to address it.
