Kernel CVEs are Alive, but Do Not Panic!
summary
The kernel community becomes a CNA and now owns CVE assignment, issuing about 13 CVEs a day while fixing roughly 40 bugs daily; a two‑of‑three public review process (with guest reviewers) assigns CVEs usually after a one‑to‑two week delay. Tooling includes a public JSON CVE repo, parsers and automation (originally bash now Rust), and helpers like stro and bippy to map commits, ranges and backports. Many CVEs come from panic‑on‑warn behavior; hardware flaws remain vendor‑assigned. Recommended action: pick up stable kernel fixes and triage only the few patches that actually affect a build.
