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 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

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.

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.
