> Multiple Linux kernel flaws in Debian trixie allow privilege escalation, data breach, and denial of service; patched in kernel 6.12.111-1.

CERT-FR has disclosed multiple vulnerabilities affecting the Linux kernel in Debian trixie versions prior to 6.12.111-1. The flaws enable three categories of attack: privilege escalation allowing unprivileged users to gain elevated system access, data confidentiality breaches, and denial-of-service conditions. The advisory references over 40 distinct CVE identifiers spanning CVE-2024-52560 through CVE-2026-89726, indicating a significant collection of kernel-level issues. Debian has published a security bulletin with patches available in kernel version 6.12.111-1 and later. Defenders running Debian trixie should apply the kernel update immediately to mitigate these risks.
