> 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.
