## Products affected

Threadlinqs normalises CPE and CNA product records across all 24 CVEs; 1 distinct zephyrproject product is affected. The most frequently affected:

- zephyr — 24 CVEs

## Threat activity

No tracked threat campaign references zephyrproject products or CVEs yet. Vulnerability records are still monitored for exploitation and linked as campaigns are ingested.

## How to prioritise zephyrproject patching

This order follows the data Threadlinqs holds for zephyrproject, not a generic severity checklist:

- No zephyrproject CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-8023](https://intel.threadlinqs.com/cve/CVE-2026-8023) (0.7%), [CVE-2026-10665](https://intel.threadlinqs.com/cve/CVE-2026-10665) (0.4%), [CVE-2026-10666](https://intel.threadlinqs.com/cve/CVE-2026-10666) (0.3%).
- 0 CVEs score Critical and 8 High on CVSS v3 (maximum 8.4, average 5.8); sequence these after KEV and high-EPSS items.
- 2 CVEs have a public exploit or proof of concept recorded, which shortens the time from disclosure to attack.

## About this data

Vendor attribution comes from the CNA and CPE product records of each CVE, folded to one vendor name; CVSS, EPSS and KEV status are read from the Threadlinqs CVE catalog; campaign and actor links come from tracked threat records. Counts reflect the data as of 2026-10-05 and refresh daily.
