Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect enforcement of Sentinel Role Governing Policy. A remote user can create a Role Governing Policy (RGP) in one namespace and use it to restrict resources in another, non-child namespace.

Sentinel RGP’s can be set by users authorized to write to the /sys/policies/rgp endpoint. These policies can be used to restrict or deny access to resources, but cannot grant additional access. As a result, this vulnerability is limited to denial of service.
