CVE-2016-9040

Estado: ModificadaMedia (5.5)—

An exploitable denial of service exists in the the Joyent SmartOS OS 20161110T013148Z Hyprlofs file system. The vulnerability is present in the Ioctl system call with the command HYPRLOFSADDENTRIES when used with a 32 bit model. An attacker can cause a buffer to be allocated and never freed. When repeatedly exploit this will result in memory exhaustion, resulting in a full system denial of service.

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).
