Multiple vulnerabilities in Ubuntu Linux kernel affecting data integrity, security policy, and remote code execution
Numerous security vulnerabilities have been discovered in the Ubuntu Linux kernel, including those that allow an attacker to execute arbitrary code, compromise data integrity, and bypass security policies. These multiple flaws underscore significant risks in Ubuntu kernel versions prior to the latest patches. Ubuntu has released a comprehensive set of security bulletins (USN-9002-1 through USN-9035-1) addressing these issues, with detailed version and fix information. Defenders are strongly advised to consult the official Ubuntu Security Notices and apply all relevant updates to mitigate exploitation risks.

A vulnerabilidade
The CERT-FR advisory covers a large batch of vulnerabilities in the Ubuntu Linux kernel, with about 200 CVEs ranging from CVE-2017-9986 to CVE-2026-46208. It says some of them allow arbitrary code execution, data integrity violations and security policy bypass, and it lists the vendor's impact as unspecified. The excerpt does not break down the flaws one by one, so per-CVE components, attacker requirements and severity are not available here. Fixes are shipped in Ubuntu Security Notices USN-9002-1 through USN-9035-1, published 6 to 10 November 2026. Affected and fixed kernel versions are in those notices, not in this excerpt.
Como foi descoberta
The articles do not say how these flaws were found. They only say that Ubuntu published its security notices on 6 and 10 November 2026 and that CERT-FR issued an advisory pointing to them. Many of the CVE IDs are old (for example CVE-2017-9986 and CVE-2022-1205), so the batch appears to bundle flaws disclosed at different times, but the articles do not explain this.
