Severity: includes CVE-2026-35385 (CVSS 3.1 AV:N … C:H/I:H/A:H) and CVE-2026-3497 (CVSS 4.0); the rest local/low.

Verified probe 2026-10-21: ssh -o BatchMode=yes dank@192.168.0.40 → Permission denied (publickey,password)
— key auth is not installed for that account, and the same box answers on both addresses (nmap banner
OpenSSH_10.0p1 Ubuntu-2ubuntu12.1, Ubuntu 24.04.4 LTS). The seven CVEs below all name a fix build of the
10.0p1 source package itself:

CVE Fixed in
CVE-2025-61984, CVE-2025-61985 1:10.0p1-5ubuntu5.1 (USN-8090-1)
CVE-2026-3497 1:10.0p1-5ubuntu5.1 (USN-8090-1)
CVE-2026-35385, CVE-2026-35386, CVE-2026-35387, CVE-2026-35414 1:10.0p1-5ubuntu5.4 (USN-8222-1)

Action: the audit's P0 key rollout to this box first (it is the only host that still refuses keys), then
apt-get upgrade past 1:10.0p1-5ubuntu5.4 — and give it a name in the inventory instead of two addresses and
an unknown OS, which is why the rest of its package set is unverified.

Taking ownership (agent). Blocked on one interactive step: the key rollout to the dank account on danklivingroom needs Frank's password once (or his authorized_key push); after that the upgrade past 1:10.0p1-5ubuntu5.4 runs. Also giving the box an inventory name.
