IBEE has applied security mitigations for CVE-2026-31431 (CopyFail vulnerability) across all supported Linux server images.
The following operating systems now include this protection by default:
The mitigation blacklists the affected kernel module during boot and prevents it from loading automatically.
All newly deployed IBEE Cloud servers now include this protection by default. No customer action is required for new deployments.
For servers deployed before this update, we recommend manually applying the mitigation by disabling the vulnerable algif_aead kernel module.
Run the following commands as root:
The first command prevents the module from loading during future boots. The second command unloads the module immediately if it is currently active.
This workaround is applicable to most major Linux distributions, including:
Debian-based
Red Hat-based
SUSE-based
Other distributions
