udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

Did this affect your environment?Answering needs an account.

What it is stated by the CNA

Broadcom based cable modems across multiple vendors are vulnerable to a buffer overflow, which allows a remote attacker to execute arbitrary code at the kernel level via JavaScript run in a victim's browser. Examples of affected products include Sagemcom F@st 3890 prior to 50.10.21_T4, Sagemcom F@st 3890 prior to 05.76.6.3f, Sagemcom F@st 3686 3.428.0, Sagemcom F@st 3686 4.83.0, NETGEAR CG3700EMR 2.01.05, NETGEAR CG3700EMR 2.01.03, NETGEAR C6250EMR 2.01.05, NETGEAR C6250EMR 2.01.03, Technicolor TC7230 STEB 01.25, COMPAL 7284E 5.510.5.11, and COMPAL 7486E 5.510.5.11. receipt

"Matches n of m" counts the attributes the two records can both be compared on: the CVSS metrics they share a version of, any weakness class beyond this one, and the vendor. fit-rules@v1

4490 records in this class held. The six above are drawn from the ones CISA has listed as exploited, ranked by how much of the record matches this one. That is why every one of them is KEV-listed: the pool is, so the colour on those spokes says nothing the pool has not already said.

No curated product neighbourhood is held for this product, so the records above are the nearest this index can name. The neighbourhood table covers a small set of products and is extended by hand.
