CVE-2022-47630

Estado: ModificadaAlta (7.4)—

Trusted Firmware-A through 2.8 has an out-of-bounds read in the X.509 parser for parsing boot certificates. This affects downstream use of get_ext and auth_nvctr. Attackers might be able to trigger dangerous read side effects or obtain sensitive information about microarchitectural state.

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).
