EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 98% 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.

Observable Timing Discrepancy in the AMD Vitis Libraries ECDSA secp256k1 component could allow attackers with local access to potentially perform timing analysis or electromagnetic emanation attacks, resulting in high confidentiality and integrity impact due to the exposure of private cryptographic keys.
