CVE-2022-31223
Estado: ModificadaBaja (2.3)—
Dell BIOS versions contain an Improper Neutralization of Null Byte vulnerability. A local authenticated administrator user could potentially exploit this vulnerability by sending unexpected null bytes in order to read memory on the system.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N
- Puntuación base: 2.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.18%
- Percentil entre todas las CVEs puntuadas: 7
- 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).
