Estado: ModificadaCrítica (9.8)—

An outbound read/write vulnerability exists in XPLATFORM that does not check offset input ranges, allowing out-of-range data to be read. An attacker can exploit arbitrary code execution.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
