Multiple Privilege Escalation and Data Confidentiality Vulnerabilities in Debian Linux Kernel 6.12.116-1 and Earlier
The French CERT-FR has disclosed multiple vulnerabilities in the Debian Linux kernel affecting Debian trixie versions prior to 6.12.116-1. These flaws include privilege escalation, data confidentiality breaches, and security policy bypasses. The advisory references Debian security bulletin msg00536 and three CVEs (CVE-2026-100080, CVE-2026-100081, CVE-2026-100082). Users are urged to apply patches as detailed in the official Debian security announcement. No evidence of active exploitation is reported, but the vulnerabilities pose a high risk due to their nature and kernel-level impact.
