RHSA-2026:95012: Critical: fence-agents security update

Q: Which systems should be prioritized for remediation?

Prioritize systems that have the listed fence-agents packages installed, particularly cluster environments where these scripts are used for remote power management, restarting failed nodes, or removing unreachable nodes from a cluster.

Q: Which packages are covered by this update?

The advisory lists fence-agents-all, fence-agents-common, fence-agents-kdump, and fence-agents-kubevirt, along with associated debuginfo and debugsource packages.

Q: How can I determine whether a system may be affected?

Check whether any of the packages named in the advisory are installed. The provided data does not include affected or fixed package versions, so version-level exposure cannot be determined from this advisory information alone.
