The software described in this documentation is either in Extended Support or Sustaining Support. See https://www.oracle.com/us/support/library/enterprise-linux-support-policies-069172.pdf for more information.
Oracle recommends that you upgrade the software described by this documentation as soon as possible.
The Data Execution Prevention (DEP) feature prevents an application or service from executing code in a non-executable memory region. Hardware-enforced DEP works in conjunction with the NX (Never eXecute) bit on compatible CPUs. Oracle Linux does not emulate the NX bit in software for CPUs that do not implement the NX bit in hardware.
You cannot disable the DEP feature.
