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.

IBM Spectrum Scale could allow a local attacker to cause a denial of service crashing the kernel by sending a subset of ioctls on the device with invalid arguments.

IBM Spectrum Scale 4.2.0.0 through 4.2.3.21 and 5.0.0.0 through 5.0.4.4 could allow an authenticated GUI user to perform unauthorized actions due to missing function level access control. IBM X-Force ID: 178414

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 security vulnerability. An attacker can force the Spectrum Scale mmfsd/mmsdrserv daemons to unexpectedly exit, impacting the functionality of the Spectrum Scale cluster and the availability of file systems managed by Spectrum Scale. IBM X-Force ID: 179987.
