Red Hat issued security advisories covering Linux kernel vulnerabilities that affect multiple products, including Red Hat Enterprise Linux (RHEL), RHEL Server, RHEL for Real Time, and Red Hat CodeReady Linux Builder across several versions and platforms. A related notice from the Canadian Centre for Cyber Security summarized advisories published during the reporting period and directed administrators to review Red Hat's official guidance.
The available notices do not provide specific CVE identifiers, exploitation details, or attribution, but they emphasize that affected organizations should identify impacted systems and apply the relevant Red Hat updates. The advisories are presented as routine but important remediation guidance for enterprises running Red Hat-based environments where kernel-level flaws could affect system security and stability.

The Canadian Centre for Cyber Security issued two notices warning that Red Hat had published multiple security advisories for vulnerabilities affecting several products, with a particular focus on **Linux kernel** updates. The affected offerings include **Red Hat CodeReady Linux Builder**, **Red Hat Enterprise Linux**, **Red Hat Enterprise Linux Server**, and **Red Hat Enterprise Linux for Real Time** across multiple versions and platforms. The first notice, `AV26-318`, covered Red Hat advisories released between March 30 and April 5, while the second, `AV26-341`, covered advisories published between April 6 and 12. In both cases, the Cyber Centre urged users and administrators to review the referenced Red Hat advisories and apply the necessary updates to address the disclosed vulnerabilities.

The Canadian Centre for Cyber Security issued multiple advisories urging organizations to apply vendor patches released between **February 16–22, 2026**, including updates addressing **Linux kernel vulnerabilities** impacting **Ubuntu** (16.04 LTS through 25.10) and **Red Hat** platforms (including *RHEL* and related offerings). The advisories emphasize routine but potentially high-impact exposure from unpatched kernel flaws across widely deployed enterprise and server environments, and direct administrators to review upstream vendor notices and deploy the corresponding updates. Separate Cyber Centre advisories also flagged patch requirements outside the Linux kernel: Microsoft released an update for **Microsoft Edge Stable** to remediate vulnerabilities in versions prior to `145.0.3800.70`, IBM published security advisories covering multiple products (including *Aspera Enterprise WebApps*, *Cloud Pak System*, *Storage Defender*, and others), and CISA issued ICS advisories for vulnerabilities across several industrial and IoT/OT products (including **Delta Electronics**, **GE Vernova**, **Honeywell CCTV**, **Siemens Simcenter**, and others) with recommended mitigations and updates where available. A Linux 7.0 release-candidate feature article is not a security advisory and does not materially relate to the patch/vulnerability notices in the other items.

dCERT issued advisories for **multiple vulnerabilities** affecting **Red Hat Hardened Images RPMs**, identifying the issue in notices `2026-1205` and `2026-1246`. The advisories indicate that security flaws were found in RPM packages used within Red Hat hardened container images, potentially exposing systems that rely on those images to a range of risks depending on the affected packages and deployed workloads. The publication of two separate dCERT notices suggests ongoing or updated vendor guidance around the same product area, and organizations using Red Hat hardened images should review the referenced advisories, determine which RPMs and image versions are affected, and prioritize remediation through updated packages or rebuilt images. Security teams should also verify downstream dependencies in container registries and production environments to ensure vulnerable image layers are replaced.
