The change, effective 28 September 2026, is driven by an 'explosion' of CVEs and bugs being found faster thanks to AI-assisted security research. Canonical will also aim to publish workarounds or hardening guidance within 24-48 hours of public disclosure, and users can opt into the -proposed pocket for earlier, untested fixes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How often will Ubuntu release kernel security updates starting September 28 2026? Ubuntu kernel security updates will move to a unified two-week stable release update (SRU) cycle, replacing the older 4/2 schedule from 2023. Because the cycle repeats every two weeks with overlapping phases, patches effectively arrive weekly: week one prepares and builds fixes, week two completes certification testing and releases them. The change takes effect from 28 September 2026. _Track this kind of patch-cadence shift on daily.dev so your Ubuntu update schedule never catches you off guard._ ### Why did Canonical change its Ubuntu kernel update schedule? Canonical cites an 'explosion' in discovered bugs and CVEs, driven largely by security researchers using AI models and agents to find flaws faster than before. To keep systems from sitting vulnerable for too long, Canonical is compressing its kernel patch, test, and release cycle to two weeks instead of the previous 4/2 schedule introduced in 2023 after criticism over slow Zenbleed patching. _Developers weighing how AI-accelerated vulnerability discovery reshapes patching practices can follow the story on daily.dev._ ### What should I do if there's no patch yet for a newly disclosed Ubuntu kernel vulnerability? Canonical aims to provide or document workarounds within 24 to 48 hours of a vulnerability's public disclosure, aiming to get environments into a defensible, safer state before a patch ships. If no safe workaround exists, it will point users toward general hardening steps instead. Users can also opt into the '-proposed' update pocket to get fixes earlier, at their own risk before full testing completes. _Ops teams handling urgent CVE response can keep up with vendor guidance like this via daily.dev._ ## Similar posts on daily.dev - [CVE flood pushes Ubuntu onto weekly kernel release cycle](https://daily.dev/posts/cve-flood-pushes-ubuntu-onto-weekly-kernel-release-cycle-pa0z1gdyr) · The Register · 0 upvotes · 0 comments - [Security updates for Wednesday \[LWN.net\]](https://daily.dev/posts/security-updates-for-wednesday-lwn-net--vq76ax3b5) · LWN.net · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#linux](https://daily.dev/tags/linux), [#ubuntu](https://daily.dev/tags/ubuntu) [View this post on daily.dev](https://daily.dev/posts/ubuntu-speeds-up-kernel-security-updates-because-of-ai-casbyx99p) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Ubuntu speeds up kernel security updates because of AI","url":"https://daily.dev/posts/ubuntu-speeds-up-kernel-security-updates-because-of-ai-casbyx99p","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/ubuntu-speeds-up-kernel-security-updates-because-of-ai-casbyx99p"},"datePublished":"2026-09-24T01:42:58.810Z","dateModified":"2026-09-24T17:09:55.457Z","description":"Canonical is switching Ubuntu kernel security updates to a unified two-week stable release update (SRU) cycle, effectively delivering patches weekly, replacing...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/11c4523e69068a7945a9fb320aac543b?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/11c4523e69068a7945a9fb320aac543b?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"omg! ubuntu!","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"omg! ubuntu!","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/79e495adb3c3425785b9be27969a2562","url":"https://daily.dev/sources/omgub"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/ubuntu-speeds-up-kernel-security-updates-because-of-ai-casbyx99p","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,linux,ubuntu","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"omg! ubuntu!","item":"https://daily.dev/sources/omgub"},{"@type":"ListItem","position":3,"name":"Ubuntu speeds up kernel security updates because of AI"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/ubuntu-speeds-up-kernel-security-updates-because-of-ai-casbyx99p#faq","mainEntity":[{"@type":"Question","name":"How often will Ubuntu release kernel security updates starting September 28 2026?","acceptedAnswer":{"@type":"Answer","text":"Ubuntu kernel security updates will move to a unified two-week stable release update (SRU) cycle, replacing the older 4/2 schedule from 2023.
