Ubuntu kernel CVE fixes are moving to a weekly release schedule

Ubuntu kernel CVE fixes are moving to a weekly release schedule 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.

Admins who need a kernel CVE fix sooner than the full cycle allows now have a sanctioned way to get one within a week: pull release candidates from the -proposed pocket before Canonical has run certification testing on them. Anyone running an Ubuntu fleet should plan for weekly kernel releases and decide which machines, if any, can take uncertified builds.
