CVE-2021-44968
Estado: ModificadaAlta (7.8)—
A Use after Free vulnerability exists in IOBit Advanced SystemCare 15 pro via requests sent in sequential order using the IOCTL driver codes, which could let a malicious user execute arbitrary code or a Denial of Service (system crash). IOCTL list: iobit_ioctl = [0x8001e01c, 0x8001e020, 0x8001e024, 0x8001e040,0x8001e044, 0x8001e048, 0x8001e04c, 0x8001e000, 0x8001e004, 0x8001e008, 0x8001e00c, 0x8001e010, 0x8001e014, 0x8001e018]
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.43%
- Percentil entre todas las CVEs puntuadas: 35
- Fecha de la puntuación: 6/10/2026
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).
