Description
IBM Guardium Data Protection 12.0, 12.1, 12.2 is affected by an improper validation of user-supplied pointers in the WfpMonitor kernel driver. Certain METHOD_NEITHER IOCTL handlers dereference user-controlled pointers without adequate probing and exception handling, potentially allowing a privileged local attacker to cause a system crash or perform limited kernel-memory reads.
