CVE coverage
AlmaLinux 9 CVE tracker
Noxen pulls AlmaLinux 9 CVE data from the same upstream sources Red Hat publishes against (RHEL 9 binary-compatible). NVD provides the upstream advisory; OSV's Red Hat ecosystem feed provides the rpm-level fix versions. The AlmaLinux project also publishes its own errata, which we cross-reference.

How matching works
What Noxen does for an AlmaLinux 9 host
- Reads
/etc/os-releaseto confirm AlmaLinux 9 (RHEL 9 binary-compatible). - Reads
rpm -qafor installed packages, including epoch and release. - Filters the local feed cache to OSV records tagged with ecosystem
AlmaLinux:9 / Red Hat:9, plus NVD records whose CPE matches the installed packages. - Compares installed vs fix versions using rpm version semantics (epoch:version-release).
- Emits findings only where the installed version is strictly older than the fix.

FAQ
Frequently asked about AlmaLinux 9 CVEs
How is AlmaLinux 9 different from RHEL 9 for CVE tracking?
Functionally, very little. AlmaLinux 9 is binary-compatible with RHEL 9 and rebuilds Red Hat's source packages on the same release cadence, so a fix landing in RHEL 9 lands in AlmaLinux 9 within days. Noxen matches against the Red Hat ecosystem feed plus AlmaLinux errata to pick up both channels.
How do I check AlmaLinux 9 CVEs on a host?
For a quick check: dnf updateinfo list security. For per-CVE detail with fix versions, Noxen reads rpm package state over SSH and matches against the live ecosystem feed using rpm version semantics (epoch:version-release).
Is AlmaLinux 9 still supported in 2026?
Yes — the AlmaLinux 9 lifecycle tracks RHEL 9 (active maintenance phase through May 2032). Major and minor security errata continue throughout this window.
Will Noxen flag a CVE that AlmaLinux 9 has already backported a fix for?
No. Red Hat-family distros backport security fixes without changing the upstream version number — the fix shows up as a higher release field (the part after the dash in epoch:version-release). Noxen compares the installed epoch:version-release against the fixed package version using rpm version semantics, so a host that has applied the backported errata is correctly shown as patched rather than as a false positive.
Which AlmaLinux 9 CVEs should I patch first?
Severity alone is a poor sort key. Noxen ranks findings by exposure first — a high-severity CVE in a package behind an internet-facing service outranks a critical one in a library nothing reaches — then by CVSS and EPSS. The EPSS prioritisation guide walks through the reasoning.
