CERT-FR advisory CERTFR-2026-AVI-1469: Ubuntu ships kernel updates (USN-8959-1 to USN-8968-1) for 200+ Linux kernel CVEs
CERT-FR published advisory CERTFR-2026-AVI-1469 on 6 November 2026 covering multiple vulnerabilities in the Linux kernel packages shipped by Ubuntu. According to the advisory, some of the flaws allow arbitrary code execution, a loss of data integrity and a security policy bypass, with other impacts left unspecified by the vendor. The bulletin references ten Ubuntu security notices published on 3 November 2026, USN-8959-1 through USN-8968-1, and lists more than two hundred CVE identifiers spanning issues from 2021 (CVE-2021-28714, CVE-2021-3640) to recent kernel CVEs of the 2026-53xxx series. No exploitation in the wild is mentioned, and the advisory provides no CVSS score, no prerequisite and no mapping of each CVE to a kernel subsystem. Kernel flaws of this class normally require local access or a specific hardware or protocol path, which limits the immediate operational urgency compared with a remotely reachable vulnerability.

CERT-FR advisory CERTFR-2026-AVI-1469 covers more than two hundred CVEs in the Linux kernel packages shipped by Ubuntu, ranging from 2021 (CVE-2021-28714, CVE-2021-3640) to the 2026-53xxx series. CERT-FR says some of them allow arbitrary code execution, loss of data integrity and a security policy bypass, and other impacts are not specified by the vendor. The advisory gives no CVSS score, no prerequisites and no mapping of each CVE to a subsystem. The story notes that kernel flaws of this class usually need local access or a specific hardware or protocol path, which is a general assessment and not a claim about any one CVE. Exact affected and fixed package versions are in Ubuntu notices USN-8959-1 to USN-8968-1, published on 3 November 2026.
