Host IPC namespace must not be shared.
Medium Severity
<VulnDiscussion>IPC (POSIX/SysV IPC) namespace provides separation of named shared memory segments, semaphores, and message queues. IPC namespace on the host must not be shared with the containers and remain isolated unless required. If the host's IPC namespace is shared with the container, it would allow processes within the container to view all of the IPC on the host system. This breaks the benefit of IPC level isolation between the host and the containers. Having access to the container can eventually manipulate the host IPC. Do not share the host's IPC namespace with the containers. Only containers with the proper label will share IPC namespace and this access must be documented.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
