Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1192520] Statement: This issue does affect the Linux kernel versions as shipped with Red Hat Enterprise Linux 6, 7 and Red Hat Enterprise MRG 2. Future kernel updates in the respective releases may address this issue. This issue does affect the Linux kernel versions as shipped with Red Hat Enterprise Linux 5. Red Hat Enterprise Linux 5 is now in Production 3 Phase of the support and maintenance life cycle. This has been rated as having Low security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/. kernel-3.18.8-201.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report. kernel-3.18.9-100.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. Sorry for being picky, but isn't the very existence of the /proc/<pid>/maps virtual files a security issue? Gday João, In the interest of getting your questions answered correctly (I just came across this by chance) It might be best to lodge it directly against the kernel component of the product you're asking about (Probably RHEL 7 or Fedora 21).
