Canonical says Ubuntu will start shipping kernel updates every week to reduce the delay between public Linux kernel vulnerability disclosures and patched packages reaching users. The company is replacing its prior four-week regular and two-week security kernel Stable Release Update schedule with overlapping two-week cycles that produce a release each week, and says it will aim to publish workarounds or hardening guidance within 24 to 48 hours of disclosure where fixes are not yet ready.
Why it matters: Organizations running Ubuntu should expect a faster kernel patch rhythm and may need to adjust testing and deployment processes. This matters because slower patch handling leaves systems exposed longer, especially as reported Linux kernel flaws are rising quickly.
