Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
IBM Guardium Data Protection 12.0、12.1 和 12.2 版本中存在对 WfpMonitor 内核驱动程序中用户提供的指针进行不当验证的安全漏洞。某些 METHOD_NEITHER 类型的 IOCTL 处理程序在解引用用户控制指针时，未进行充分的探测（probing）和异常处理，可能导致特权本地攻击者引发系统崩溃，或执行有限的内核内存读取操作。

Security vulnerability affects the Windows S-TAP component as part of IBM Guardium Data Protection
Source: CVE Program / CVE List V5
Vulnerability 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.
