Medium Severity
<VulnDiscussion>The NX bit is a hardware feature that prevents the execution of code from data memory regions. By enabling NX bit execute protection, OpenShift ensures that malicious code or exploits cannot execute from areas of memory that are intended for data storage. This helps protect against various types of buffer overflow attacks, where an attacker attempts to inject and execute malicious code in data memory.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
