CERT-FR: multiple Ubuntu Linux kernel vulnerabilities allow remote code execution, privilege escalation and DoS
CERT-FR published advisory CERTFR-2026-AVI-1376 on multiple vulnerabilities in the Linux kernel shipped with Ubuntu. According to the advisory, an attacker could exploit some of them to achieve remote arbitrary code execution, privilege escalation and remote denial of service. The advisory also lists impacts on data integrity and confidentiality, security policy bypass, XSS and CSRF. It aggregates a dozen Ubuntu security notices published between 13 and 15 October 2026 and references about 90 CVEs. It does not report active exploitation and gives no CVSS scores or per-CVE technical detail.
