CVE-2017-1000370
El parche offset2lib tal como es usado por el Kernel de Linux contiene una vulnerabilidad que permite que un binario PIE sea execve()'ed con 1 GB de argumentos o cadenas de entorno, entonces la pila ocupa la dirección 0x80000000 y el binario PIE se asigna por encima de 0x40000000 haciendo null la protección del parche offset2lib. Esto afecta al Kernel de Linux versión 4.11.5 y anteriores. Este es un problema diferente al CVE-2017-1000371. Este problema parece estar limitado a los sistemas basados en i386.

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.
