CVE-2022-29582

Estado: AnalizadaAlta (7)—💥 PoC

En el kernel de Linux versiones anteriores a 5.17.3, el archivo fs/io_uring.c presenta un uso de memoria previamente liberada debido a una condición de carrera en la función io_uring timeouts. Esto puede ser desencadenado por un usuario local que no tenga acceso a ningún espacio de nombres de usuario; sin embargo, la condición de carrera quizás sólo pueda ser explotada con poca frecuencia

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
