CVE coverage
Debian 11 CVE tracker
Noxen pulls Debian 11 (Bullseye) CVE data from OSV.dev's Debian ecosystem feed, which mirrors the Debian Security Tracker. Bullseye is in the Debian LTS phase (maintained by Freexian) through August 2026, so security backports still land — Noxen surfaces them with exact fix versions and matches against the installed source package.

How matching works
What Noxen does for a Debian 11 host
- Reads
/etc/os-releaseover SSH to confirm the host is on Debian 11. - Reads the dpkg package list — every binary package, plus its corresponding source package via
dpkg-query --showformat='${Source}'. - Filters the local feed cache to OSV records tagged with ecosystem
Debian:11. - For each record, compares your installed version against the OSV-published fix version using the Debian/Ubuntu version-comparison rules (epoch, upstream, debian-revision).
- Emits a finding only when the installed version is older than the fix. Where Ubuntu Pro / ESM-only fixes apply, they are flagged separately.

FAQ
Frequently asked about Debian 11 CVEs
Is Debian 11 still supported in 2026?
Yes — Debian 11 entered LTS in August 2024 (when regular Security Team support ended) and continues through August 2026 under Freexian's volunteer LTS programme. Paid ELTS coverage extends further. Backports are released for the same source packages the Security Tracker covers.
How do I check Debian 11 CVEs on a running host?
For a quick count: apt list --upgradable 2>/dev/null | grep -ci security. For a per-CVE breakdown with fix versions, Noxen reads dpkg over SSH and matches installed source-package versions against the OSV Debian:11 ecosystem feed.
What's the practical difference between Debian 11 and 12 for CVE coverage?
Same data source (Debian Security Tracker, mirrored through OSV). The difference is the package version set and what's been backported. A CVE fixed upstream in openssl 3.2 gets a separate Bullseye backport into the Bullseye-shipped 1.1.1 series and a Bookworm backport into 3.0. Noxen matches against the right per-release fix version automatically.
