CVE-2022-50189

Estado: AnalizadaAlta (7.1)—

In the Linux kernel, the following vulnerability has been resolved:

tools/power turbostat: Fix file pointer leak

Currently if a fscanf fails then an early return leaks an open file pointer. Fix this by fclosing the file before the return. Detected using static analysis with cppcheck:

tools/power/x86/turbostat/turbostat.c:2039:3: error: Resource leak: fp [resourceLeak]

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.

AV:L + PR:L sin UI indica escalada local; la fuga de recursos (CWE-772) en turbostat permite DoS o lectura de datos del kernel con privilegios elevados.

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.
