Red Hat Updates .NET 8 on RHEL 10.0 EUS
Tech GuruQuick Answer
The .NET 8 erratum addresses two vulnerabilities in the RHEL 10.0 EUS package stream. Match installed packages and support entitlements to the errata, apply the supported fixes, validate service operation, and retain evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory .NET 8 runtime and SDK packages, application deployment models, RHEL support channels and service owners. Match product, architecture, package epoch/version/release and support stream to the individual erratum; apply each CVE only where its documented prerequisites hold. Install the applicable RHSA-2026:93455 packages, including the dotnet8.0-8.0.133-1.el10_0 source package family, and restart dependent services. Verify the runtime actually loaded by each application; test authentication, data processing and integrations, and retain build and change evidence.

What Changed
The .NET 8 erratum addresses two vulnerabilities in the RHEL 10.0 EUS package stream.
What To Validate Now
- Inventory. Inventory .NET 8 runtime and SDK packages, application deployment models, RHEL support channels and service owners.
- Establish applicability. Match product, architecture, package epoch/version/release and support stream to the individual erratum; apply each CVE only where its documented prerequisites hold.
- Remediate. Install the applicable RHSA-2026:93455 packages, including the dotnet8.0-8.0.133-1.el10_0 source package family, and restart dependent services.
- Validate. Verify the runtime actually loaded by each application; test authentication, data processing and integrations, and retain build 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
Self-contained applications and container images may carry their own runtime and need a separate supported rebuild. CVSS values are the authority-provided per-CVE scores, not a score for the whole update. Retain the advisory, inventory, approval, package and validation records.
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.
