This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 99% 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.

Improper restriction of operations within the bounds of a memory buffer in the AMD secure processer (ASP) could allow an attacker to read or write to protected memory potentially resulting in arbitrary code execution.
