CVE-2022-48967
Estado: ModificadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
NFC: nci: Bounds check struct nfc_target arrays
While running under CONFIG_FORTIFY_SOURCE=y, syzkaller reported:
This appears to be a legitimate lack of bounds checking in nci_add_new_protocol(). Add the missing checks.

CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.34%
- Percentil entre todas las CVEs puntuadas: 26
- 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).
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation85 % - Impacto principal
T1565.001Stored Data Manipulationimpact75 % - Impacto secundario
T1499.004Application or System Exploitationimpact70 %
Vulnerabilidad local (AV:L, PR:L) sin interacción de usuario en kernel NFC. Buffer overflow en campo nfc_target permite sobrescritura de memoria más allá de límites, permitiendo escalada de privilegios (high integrity/availability impact). CWE-129 confirma falta de bounds checking.
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
