In fact, performing relocations against the .notes\nsection means that the KASLR base is exposed since /sys/kernel/notes\nis world-readable.\n\nTo avoid leaking the KASLR base without breaking unprivileged tools that\nare expecting to read /sys/kernel/notes, skip performing relocations in\nthe .notes section. The values readable in .notes are then identical to\nthose found in System.map."
