Nyxian 0.8.2 "Kate" Pre-Beta

Changelog

Jailed

Nyxian

• compatibility patches for older iOS versions(16.x/17.x) have been done.
• redesigned UI for older iOS to look more modern, similar to the design philosophy of Nyxian on iOS 26.x
• bootstrapping now is plist based instead of NSUserDefaults(cuz we cannot predict if its really bootstrapped without that)

Kernel Virtualization Layer (ksurface)

• fixed vulnerability where old iOS versions cause ksurface to panic because of not nullified memory (89f37b5 and aa1a379)
• fixed being able to set invalid hostnames (8b4e075)
• fixing buffer overflow vulnerability in SYS_proctb syscall (a85fe7e) (probably unreachable because of memory constraints on jailed iOS)
• fixing process structure poisoning (387258a)
• fixing latent vulnerability in SYS_gettask syscall, caused by a invalid cleanup path, but invalid because proc copy structure destruction symbol does a null pointer check (9f54fca)
• fixed task port confusion vulnerability between the SYS_gettask and SYS_sendtask syscall which could lead to mach ports being reused that were used by other processes. (6dc19a6)

Nyxian 0.8.1 "Kate" Pre-Beta

EXTREMELY NECESSARY UPDATE

Changelog

• Fixed LDEThreadController object leak causing infinite pthreads to be created
• Fixed sub iOS 26.0 crash in code editor

Nyxian 0.8.0 "Kate" Pre-Beta

Changelog

• Added support for 3D rendering frameworks (simd fix)
• Implemented hardened kernel virtualization layer
• Introduced pointers to the kernel virtualization layer
• Improved a lot of kernel APIs
• Improved compilation speed(introduced LDEGroupThreadController and LDEThreadController that now work way more managed by the mach API)
• Added actual syscall translation to the kernel virtualization layer that will entirely replace the ServerSession NSXPC proxy
• Fixed a ton of race conditions and logic vulnerabilities
• Improved design a lot(especially in app switcher)
• Fixed UNIX semantics(we were treating ruid as euid ;w;)
• Resecuring instead of bypassing the NSExtension security
• Fixed(again) gethostname and sethostname

Notes

In 0.9.x aka the beta of Nyxian we introduce swift support to Nyxian. swift is a mess to patch and optimize for use in iOS and we actually care about user experience.

Nyxian Alpha 20251128a

Changelog

• Fixed keyboard toolbar not floating on iOS 26.
• Changed application template to use SceneDelegate lifecycle and to be 1:1 with apples swift template.
• Updated Nyxian to use SceneDelegate lifecycle.
• Fixed up appearance of menus and UI elements in iOS 26
• Replaced blur effect with glass effect on app switcher iOS 26

Nyxian Alpha 20251127a

Changelog

UI & UX

• Added modernized iOS 26 UI
• Rewrote XCButton in ObjC
• Added a app switcher button for iOS 26

Kernel Virtualization Layer

• Fixed vulnerability #14 "Daemon endpoint override" (Addressed with improved logic checks)
• Fixed vulnerability #15 "Duplicated process entries" (Addressed with improved logic checks)
• Improved proc api

Note

Although the changelog is not that big the change in Nyxian is huge. The fixed vulnerabilities caused tremendous trouble, Nyxians stability is tremendously improved in this build!

Nyxian Alpha 20251125a

Changelog

• Fixed some problems with utility support, such as the keyboard not appearing(next build I gonna fix the touch problems on LDEWindowSessionTerminal dw)
• Fixed iPhone support of Nyxian.
• Replaced seqlock with my new low level reflock which makes Nyxians kernel API much more lightweight and easy to use, less prone to fail.
• Added headless application v2, the new one is not hook based anymore.
• Fixed the full screen stutter some people reported on the bottom of their screens.
• Added entitlement config to projects, now you can set nyxian entitlements directly at development of your apps.
• Switched to iOS 26 SDK.
• Added a new project config key LDEVersion which sets the version you wanna target as the highest iOS version, if you dont want Liquid Glass in your app then you shall set it to 18.5 for example while LDEMinimumVersion sets the version you wanna have at minimum.
• Fixed a few more sysctl syscalls such as KERN_PROC_PID,KERN_PROC_UID and KERN_PROC_RUID.
• Made killing processes which have more Childs faster and more efficient, shall be now 2.5 times faster, than before.
• Fixed a vulnerability regarding PEEntitlementProcessElevate in which a process while elevation triggers on a other thread the same elevation which causes unexpected process structure corruption, was addressed by implementing reflock as mentioned above.
• Added PEEntitlementPlatform as a security feature to harden daemons in the process model so normal processes cannot interact with them like with normal processes running in Nyxian.
• Added PEEntitlementProcessSpawnInheriteEntitlements as another security feature to prevent privilege escalations, such as a sandboxed process executing a application that has at trust cache level more entitlements, if a vulnerability exists in the privileged binary then the sandboxed process could easier exploit that. While that daemons and nyxian doesnt have that entitlement set in its entitlement layer, because Nyxian shall not inherit its entitlements to the child process lol. Its a curse of unbinding entitlement, when a process has it all process it spawns have the same entitlements as it self 1:1.
