Multiple vulnerabilities in Debian LTS Linux kernel
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
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.

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 its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,853 reports from 146 sources, 616 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. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
