> Multiple Linux kernel flaws across Red Hat Enterprise Linux versions allow arbitrary code execution, privilege escalation, and remote denial of service.

CERT-FR has published an advisory covering multiple vulnerabilities discovered in the Linux kernel affecting Red Hat Enterprise Linux and Red Hat CodeReady Linux Builder across all supported architectures (x86_64, aarch64, ppc64le, s390x) and versions (8 through 10 with various support lifecycles). The vulnerabilities enable attackers to achieve arbitrary code execution, privilege escalation, remote denial of service, data integrity compromise, data confidentiality breach, and security policy bypass. Red Hat has released kernel patches across ten separate security bulletins (RHSA-2026:67114, RHSA-2026:67277, RHSA-2026:67468, RHSA-2026:67469, RHSA-2026:67470, RHSA-2026:67471, RHSA-2026:67723, RHSA-2026:68100, RHSA-2026:68131, RHSA-2026:68507, RHSA-2026:68532) published between 14-17 September 2026. The advisory references 70 distinct CVE identifiers spanning 2024 through 2026, indicating a significant accumulation of kernel-level issues across multiple release cycles. The breadth of affected versions and architectures means organizations running any version of RHEL 8, 9, or 10 require kernel patching.
