CERT-FR has published a security advisory covering multiple vulnerabilities in the Linux kernel shipped with Debian trixie. The affected versions are those prior to 6.12.107-1. These vulnerabilities permit attackers to achieve privilege escalation, compromise data confidentiality, and cause denial of service. The advisory references twelve distinct CVEs spanning CVE-2025-40074 through CVE-2026-80725. Debian has published a security bulletin with patched kernel versions available for download and installation. Defenders running Debian trixie should prioritize updating to the patched kernel version to mitigate the risk of local privilege escalation and system compromise.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
