CVE-2026-84290: IBM Guardium Data Protection

Medium severity, CVSS 5.1. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• IBM Guardium Data Protection: version 12.0 only; version 12.1 only; version 12.2 only
