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.
