## What to check

- Applies to: The 3 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR issued an advisory regarding multiple vulnerabilities discovered in the Linux kernel as shipped in Debian trixie, affecting versions prior to 6.12.116-1. The vulnerabilities, tracked as CVE-2026-100080, CVE-2026-100081, and CVE-2026-100082, could allow an attacker to achieve privilege escalation, compromise data confidentiality, bypass security policy restrictions, or cause a denial of service.

No evidence of active exploitation is mentioned in the advisory. Debian published corresponding security fixes via its official security announcement (msg00536, dated November 8, 2026). Defenders running Debian trixie should update affected systems to kernel version 6.12.116-1 or later as referenced in the Debian security bulletin.

This is a routine distribution-level kernel patch advisory with no indication of in-the-wild exploitation or targeted campaign activity.
