EchelonGraph scoreMEDIUM confidence

This low-severity CVE scores 2.0 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 91% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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

A transient execution vulnerability within AMD CPUs may allow a local user-privileged attacker to leak data via the floating point divisor unit, potentially resulting in loss of confidentiality.
