Descriptions

The Spectrum Scale 4.2.0.0 through 4.2.3.21 and 5.0.0.0 through 5.0.4.3 file system component is affected by a denial of service vulnerability in its kernel module that could allow an attacker to cause a denial of service condition on the affected system. To exploit this vulnerability, a local attacker could invoke a subset of ioctls on the Spectrum Scale device with non-valid arguments. This could allow the attacker to crash the kernel. IBM X-Force ID: 179986.

El componente filesystem de Spectrum Scale versiones 4.2.0.0 hasta 4.2.3.21 y versiones 5.0.0.0 hasta 5.0.4.3, está afectado por una vulnerabilidad de denegación de servicio en su módulo kernel que podría permitir a un atacante causar una condición de denegación de servicio en el sistema afectado. Para explotar esta vulnerabilidad, un atacante local podría invocar un subconjunto de ioctls en el dispositivo Spectrum Scale con argumentos no válidos. Esto podría permitir a un atacante bloquear el kernel. IBM X-Force ID: 179986.
