Red Hat Updates Kernel, curl, libxml2, and osbuild-composer
Tech GuruQuick Answer
Red Hat published four RHEL errata for kernel, curl, libxml2, and osbuild-composer. Inventory exact products and support streams, install only the matching errata packages, reboot where required, validate dependent services and image builds, and retain evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory affected RHEL 8, 9.2 E4S, and 10.0 EUS systems, exact packages, repositories, kernel boot entries, image-builder services, owners, and maintenance windows. Match each system and package to its individual RHSA and support stream; do not treat this grouped notice as one package set for every RHEL host. Install the advisory-listed signed packages from the correct Red Hat repositories, reboot kernel systems into the fixed build, and restart dependent services where the errata requires it. Confirm installed and running versions, test network clients, XML consumers and image composition, review failed transactions or boot issues, and retain repository and change evidence.

What Changed
Four Red Hat errata update the RHEL kernel, curl, libxml2, and osbuild-composer on specific base and extended-support streams.
What To Validate Now
- Inventory. Inventory affected RHEL 8, 9.2 E4S, and 10.0 EUS systems, exact packages, repositories, kernel boot entries, image-builder services, owners, and maintenance windows.
- Establish applicability. Match each system and package to its individual RHSA and support stream; do not treat this grouped notice as one package set for every RHEL host.
- Remediate. Install the advisory-listed signed packages from the correct Red Hat repositories, reboot kernel systems into the fixed build, and restart dependent services where the errata requires it.
- Validate. Confirm installed and running versions, test network clients, XML consumers and image composition, review failed transactions or boot issues, and retain repository and change evidence.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
These packages span unrelated runtime paths and extended-support channels. Stage kernel reboots and application tests, and never substitute a package from another RHEL stream.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
