dirtyZero v1.0.1 iOS Customization Guide: Install No Jailbreak (2025)

Complete guide to installing dirtyZero IPA using Esign iOS/Sideloadly. Learn compatible versions, safety tips, and customization features for iOS 16-18.3.2 devices.

What is dirtyZero?

dirtyZero is a basic iPhone/iPad customization app created using CVE-2025-24203. The bug was patched in iOS 18.4, so you can’t use this AppApp for customization if you are on the latest version of iOS 18.5 and up.

Tip: Try to find the best jailbreak tool for iOS 18.5 and up devices – Zeejb Jailbreak Finder Tool.

The CVE-2025-24203 code and writeup describe a vulnerability in the XNU kernel (used by macOS) that allows an unprivileged process to modify read-only memory pages, specifically those backed by a file, by exploiting the VM_BEHAVIOR_ZERO_WIRED_PAGES behavior.

This exploit allows temporary filesystem modifications through VM_BEHAVIOR_ZERO_WIRED_PAGES flag manipulation, a memory management flaw Apple patched in 2025.

Temporary Filesystem mechanism is similar to the MacDirtyCow bug, which means the attacker is using the small time gap between the read-only page being checked and replaced.

What can we do with dirtyZero?

This vulnerability allows an unprivileged process to write zeros to physical memory pages that it should not be able to modify, specifically, pages backed by files (via the vnode pager) or other delay-copy objects.

This App allows users of iOS 18.4 and below to hide the Home Bar and Dock. It also allows users to apply multiple tweaks at once, so you can enable more than one tweak and use them all at once by instant respring.

In the springboard, users can hide folder backgrounds, widget config backgrounds, Applibrary backgrounds, Spotlight backgrounds, Alert & Touch backgrounds, and hide docks.

Also, on the lock screen, users can hide the password background.

The AppApp features three main buttons: Apply, Revet, and Respring. Once you enable the tweaks, if something goes wrong, you can use the Revert button or manually restart your iPhone/iPad to revert the changes, because the tweaks are done in memory. This means that with each restart, you need to enable tweaks like semi-untethered Jailbreak tools ( unc0ver, Chimera, Dopamine)
