> Multiple kernel flaws affecting Debian LTS 12 allow privilege escalation, data confidentiality breaches, and denial of service.

CERT-FR has published an advisory covering multiple vulnerabilities discovered in the Linux kernel used by Debian LTS 12 (Bookworm), affecting versions prior to 6.1.187-1. The advisory identifies dozens of CVEs spanning 2023 through 2026, with impacts including privilege escalation, confidentiality violations, and denial-of-service conditions. The Debian LTS project has released patched kernel versions addressing these issues. Debian LTS administrators should apply the security update immediately, as the kernel is a critical infrastructure component and privilege-escalation vulnerabilities in it can grant attackers complete system control.
