CVE-2026-4017

Estado: AplazadaAlta (7.4)—

Buffer Overflow in the entry handler of the TraceEvent() system call could allow an attacker with local access to cause information disclosure, data tampering or a crash of the QNX Neutrino kernel.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Buffer overflow local (AV:L, PR:N, UI:N) sin interacción en syscall permite escalada a ejecución de código kernel, información disclosure y DoS. CWE-121 confirma desbordamiento de buffer con potencial RCE.

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.
