You might want to reconsider that policy decision :)
Hi Greg, While some risk is inherent, we believe the potential for abuse here is limited, especially given the existing CAP_SYS_ADMIN requirement. But, even with root access compromised, this tool presents a smaller attack surface than alternatives like crash/drgn. It exposes less sensitive information, unlike crash/drgn, which could potentially allow reading all of kernel memory. Pasha
