dirtyZero
dirtyZero lets you hide the Dock and Home Bar on iOS 18.3.2 and below—no jailbreak needed.
The dirtyZero app uses a newly discovered iOS vulnerability (CVE-2025-24203) to let users hide the Dock and Home Bar on iOS 18.3.2 and earlier—no jailbreak needed.
Unlike older exploits like MacDirtyCow, this one can’t write custom data. Instead, it clears (or “zeros out”) parts of the system’s read-only memory, which can still lead to system tweaks or even instability. This behavior is tied to a flaw called BEHAVIOR_ZERO_WIRED_PAGES, allowing limited but impactful access to protected areas of the system.
Although Apple seems to have patched the bug in iOS 18.4, they didn’t mention it in the update notes, so it’s unclear if all devices are fully protected. For now, dirtyZero is a proof-of-concept focused on UI tweaks like hiding system elements, but more features could come in future updates.
⚠️ Security Notes:
- Devices running iOS 18.3.2 or earlier are vulnerable.
- iOS 18.4+ users are likely safe, but Apple’s vague patch notes leave some uncertainty.
- Even limited access to protected memory is a risk—it can be misused to bypass security or modify system behavior.
✅ Recommendation:
If you want to stay secure, update your iPhone or iPad to iOS 18.4 or later and avoid using apps that rely on unpatched exploits like dirtyZero.
