Noroxi assessment
Priority: Monitor (action score 19/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 9.1% (FIRST EPSS); higher than 95.2% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: bind9 (Debian:12) 1:9.7.2.dfsg.P3-1; bind9 (Debian:5.0) 1:9.6.ESV.R3+dfsg-0+lenny1; bind (openSUSE:Tumbleweed) 9.10.3P4-21.1.
Low priority for now. Upgrade to bind9 (Debian:12) 1:9.7.2.dfsg.P3-1; bind9 (Debian:5.0) 1:9.6.ESV.R3+dfsg-0+lenny1; bind (openSUSE:Tumbleweed) 9.10.3P4-21.1 or later.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
