No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (National Instruments) lists measX DASYLab versions before 2026.0.0 as affected. No release containing a fix is confirmed on record.

There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data.   This results in a read a few bytes past the end of an allocated heap buffer during file handling.  Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file.  This issue affects all versions before 2026.0.0.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Data Freshness Timeline

(refreshed 17× in last 7d / 99× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 100 of 140 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 40 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

CVE-2026-64198 is a high-severity vulnerability; its CVE record was published on September 3, 2026. There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data. This results in a read a few bytes past the end of an allocated heap buffer during file handling. Successful exploitation requires an attacker to get a user to open a specially crafted .DSB…
When was the CVE record for CVE-2026-64198 published?
The CVE record for CVE-2026-64198 was published on September 3, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of September 22, 2026; the record at its source may have been updated since.
Is CVE-2026-64198 actively exploited?
CVE-2026-64198 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.2% probability of exploitation in the next 30 days (4th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-64198?
CVE-2026-64198 has a CVSS v3 base score of 7.3 (NVD). EchelonGraph synthesises NVD + CISA KEV + FIRST EPSS + GHSA into a combined EG score of 7.8 (HIGH).
How do I remediate CVE-2026-64198?
No fix for CVE-2026-64198 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (National Instruments) lists measX DASYLab versions before 2026.0.0 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-64198 are linked in the Vendor Advisories panel on this page.
