Multiple Vulnerabilities in Oracle Solaris and Sun ZFS Storage Allow Remote Code Execution
Summary
CERT-FR published advisory CERTFR-2026-AVI-0471 on 22 April 2026 disclosing multiple vulnerabilities in Oracle Systems products. The affected systems are Oracle Solaris version 11.4 and Sun ZFS Storage Appliance Kit version 8.8. The vulnerabilities enable remote arbitrary code execution and denial of service attacks. Organizations running these Oracle products should refer to Oracle's Critical Patch Update cpuapr2026 (published 21 April 2026) for available patches and remediation guidance.
“De multiples vulnérabilités ont été découvertes dans Oracle Systems.”
Organizations running Oracle Solaris 11.4 or Sun ZFS Storage Appliance Kit 8.8 should treat this advisory as requiring immediate action given the remote code execution risk. Even if systems are not directly internet-exposed, CVE-2024-6387 is a known regreSSHion vulnerability with active exploitation history; any lateral movement from an initial compromise could reach these systems. Patch verification should be incorporated into next maintenance cycles.

What changed
CERT-FR issued a security advisory documenting multiple remote code execution and denial-of-service vulnerabilities in Oracle Solaris 11.4 and Sun ZFS Storage Appliance Kit 8.8. The vulnerabilities are traced to Oracle's Critical Patch Update cpuapr2026 released on 21 April 2026. No patches are provided in the advisory itself; organizations must obtain fixes from Oracle's security bulletin.
Affected parties—primarily enterprise and government operators of Oracle Solaris servers and Sun ZFS storage appliances—should prioritize applying the Oracle patches referenced in the advisory. The CVEs (CVE-2024-6387 and CVE-2026-34281) provide additional reference for vulnerability tracking and patching workflows.
