Feels like the more sensible process would be for kernel maintainers to announce when a version contains a fix for a high-impact security vulnerability and for distro maintainers to pay attention to that. Could be done without revealing what the vulnerability actually is in most cases, trusting the kernel maintainer's judgement. There does seem to be a public linux-cve-announce mailing list.
No it can’t. The bad actors that should actually worry most people are actively combing through commits on mainstream codebases, using a combination of automation/AI and manual review to pluck vulns out by their remediations.
This is true no matter what, but the comment I’m replying to was also pitching that maintainers actively call out that the patch includes a high sev security fix:
