CVE-2017-17320

Estado: ModificadaAlta (7.8)—

Huawei Mate 9 Pro smartphones with software of LON-AL00BC00B139D, LON-AL00BC00B229, LON-L29DC721B188 have a memory double free vulnerability. The system does not manage the memory properly, that frees on the same memory address twice. An attacker tricks the user who has root privilege to install a crafted application, successful exploit could result in malicious 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).
