Our Response to CVE-2026-31431
Around the same time we were dealing with the cPanel CVE-2026-41940, we became aware of the Linux kernel local privilege escalation vulnerability – CVE-2026-31431 (Copy Fail) affecting all Linux kernels since 2017.
Here’s how we responded:
- 30th April / 01 May 2026 – Confirmed mitigation recommendations were in place on all servers
- 04th May 2026 – 12:42 AM AEST: We applied the latest kernel as advised by Cloud Linux
Result: No evidence of any successful compromise was found on any myshophosting server.
We will continue to monitor the situation and will provide follow up blog posts should they be required.
