Linux Kernel capabilities must be restricted within containers.
Medium Severity
<VulnDiscussion>By default, MKE starts containers with a restricted set of Linux Kernel Capabilities. Any process may be granted the required capabilities instead of root access. Using Linux Kernel Capabilities, the processes do not have to run as root for almost all the specific areas where root privileges are usually needed. MKE supports the addition and removal of capabilities, allowing the use of a nondefault profile. Remove all capabilities except those explicitly required for the user's container process. By default, below capabilities are available for Linux containers: AUDIT_WRITE CHOWN DAC_OVERRIDE FOWNER FSETID KILL MKNOD NET_BIND_SERVICE NET_RAW SETFCAP SETGID SETPCAP SETUID SYS_CHROOT</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
