Ubuntu kernel CVE fixes are moving to a weekly release schedule
Canonical will ship Ubuntu kernel updates weekly by overlapping two-week cycles, with uncertified -proposed builds for faster CVE fixes.
Canonical is merging Ubuntu's four-week Stable Release Update cycle and its two-week security cycle into overlapping two-week cycles, so a kernel build is published every week. After a cutoff, the first week covers kernel builds and smoke tests that land in the -proposed pocket, and the second week covers certification before the kernels are released. Admins who cannot wait may install those uncertified release candidates and own any regression risk. Where a safe workaround exists, Canonical still aims to publish it within 24 to 48 hours of public disclosure.
- Overlapping two-week cycles produce a weekly Ubuntu kernel release.
- Uncertified -proposed builds are the path to fixes within a week.
- Certification still runs; skipping it leaves regressions to the adopter.
- Safe workarounds are targeted within 24 to 48 hours of disclosure.

Ubuntu kernels will ship every week under a new release schedule from Canonical, which is merging its four-week cycle for regular Stable Release Updates (SRUs) and its two-week cycle for security fixes into a single two-week cycle. The cycles overlap, each starting a week after the one before, which is what produces a weekly release.
