CVE-2018-19086

Estado: ModificadaAlta (7.8)—

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E040 with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges.

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).
