1 fonte(s) · 1 atualização(ões) · publicado 15/10/2026 21:00 · coletado há 2 dias

CERT-FR advisory CERTFR-2026-AVI-1333, published 16 October 2026, reports multiple vulnerabilities in the Ubuntu Linux kernel. Per the advisory, some of them allow an attacker to achieve remote arbitrary code execution, privilege escalation and compromise of data confidentiality. The advisory also lists data integrity compromise and security policy bypass as impacts. It is based on about 22 Ubuntu security notices (USN) published between 8 and 15 October 2026. It gives no exploitation status, IOCs or attribution. The CVE list is very long, mixing older CVEs (2017-2025) with many 2026 CVEs, and the source text is truncated.

Detalhes técnicos

  • Impacts listed by CERT-FR: remote arbitrary code execution, privilege escalation, confidentiality and integrity compromise, security policy bypass.
