We have updated our latest Linode kernel to version 7.0.5, which contains the upstream fix from kernel.org for the DirtyFrag vulnerabilities as well as the previous fixes for the recent CopyFail vulnerability. This kernel is available in Cloud Manager and we recommend customers using the Linode-compiled kernel update their configurations to this kernel. We are in parallel tracking the upstream Linux distributions and will provide another update when fixed versions have been released.

Akamai is aware of the recently disclosed “DirtyFrag”[1] vulnerability that followed the “CopyFail”[2] disclosure. This vulnerability is very similar in nature and has a similar impact, exploit path, and mitigation approach. We have not observed any related malicious exploits targeting our infrastructure and are continuing to address the vulnerability across our product portfolio and internal systems. As with “CopyFail”, we are advising customers to consider most Linux distributions to be at-risk until patched. Since the “DirtyFrag” vulnerability was disclosed prior to upstream patches hav

What to do next
- Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
- Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.
- Watch the provider going forward. Follow Linode's status feed →
GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
