EPICS Base maintenance guidance
CVE-2026-114595 affects EPICS Base releases through 7.0.10 under the documented network request-processing condition. CISA rates the issue Critical and identifies EPICS Base 7.0.11 as the supported update. This guidance is intended for industrial and control-system owners, integrators, and administrators coordinating maintenance with operational stakeholders.
The advisory describes potential memory corruption, service disruption, and remote code execution. Network reachability is part of the vulnerability condition, but it does not establish exposure in any particular environment. CISA reports no known public exploitation specifically targeting this issue in the supplied advisory context.
Read the official CISA advisory for the authoritative affected-version and update information.
Who should assess this update
Assess systems that use EPICS Base at 7.0.10 or earlier, especially where the documented processing condition may be reachable within the intended operating environment. Do not infer installed versions, reachability, or exposure from this advisory alone.
EPICS deployments commonly sit within coordinated operational environments. Include control engineers, system owners, integrators, cybersecurity personnel, and change-management stakeholders in the assessment. Confirm the deployed release and applicable support commitments using trusted local inventory and vendor or integrator records.
Plan a supported, coordinated update
- Establish whether the deployment is affected and whether 7.0.11 is compatible with the organization’s supported EPICS Base branch and dependent operational components.
- Use the organization’s approved change-control process, maintenance window, communications plan, and operational acceptance criteria.
- Review vendor, integrator, and equipment-owner guidance before changing a production control environment. Coordinate any required safety, availability, or process-state precautions.
- Define a recovery decision point before maintenance begins. Readers should retain their own approved recovery materials and use their established restoration process if acceptance criteria are not met.
- Where EPICS components are operated on managed virtual infrastructure, align the maintenance plan with the responsible platform team and its documented service procedures.
Safe checks before and after maintenance
Before the change
Record the deployed EPICS Base release, ownership, approved maintenance scope, dependencies, expected operating behavior, and rollback authority. Confirm that the planned update is 7.0.11 and that all participating teams understand the maintenance and recovery decision points.
After the change
Confirm the installed release against trusted local administration records, then perform the organization’s approved functional and operational checks. Review expected service health and operational telemetry for unexpected changes, and document the result through the normal change record. A successful update should not be assumed solely from completion of maintenance activity.
Operational compatibility and recovery
For industrial systems, compatibility and coordinated maintenance matter as much as the software version. Validate the update in a representative, authorized environment when the organization’s process requires it, and schedule production work only after required stakeholders accept the plan. Preserve the ability for readers to follow their own approved recovery procedures; this guidance does not replace equipment-owner, integrator, or site safety requirements.
