Debian Patches Dozens of Linux Kernel Flaws
Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
CERT-FR advisory lists over 200 Linux kernel vulnerabilities in Debian 13 (trixie) fixed in version 6.12.113-1; patch now, no active exploitation reported.
CERT-FR has published an advisory covering a very large batch of vulnerabilities affecting the Linux kernel as shipped in Debian 13 (trixie), affecting all versions prior to 6.12.113-1. The advisory consolidates over 200 individual CVE entries referenced in Debian Security Advisory DSA msg00482 (16 October 2026), covering a wide range of kernel subsystems. Collectively, the flaws permit attackers with local access to achieve privilege escalation, cause denial of service, and in some cases read sensitive kernel memory or data (confidentiality impact).
No evidence of in-the-wild exploitation is mentioned in the advisory; this is a routine (if unusually large) vendor patch bulletin rather than a report of active attacks. Defenders running Debian 13 should prioritize updating affected kernel packages to 6.12.113-1 or later via the standard Debian security repository, as reflected in the referenced Debian Security Announce mailing list post. Given the sheer volume of CVEs bundled into a single kernel update, organizations should treat this as a standard but high-priority patch cycle for all Debian trixie hosts, verifying kernel version post-update and rebooting affected systems to apply the fix.
No specific threat actor, campaign, or malware is associated with this disclosure; it is a vulnerability coordination/patch advisory only. Due to the scale of the list, only a representative subset of the most notable CVE identifiers is included below; the full enumeration should be obtained from the primary Debian security bulletin linked in the advisory.

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 14,067 reports from 142 sources, 531 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 — about forty a week that are yours, not the four hundred that are not.
