I've published a write-up on reversing and analyzing Samsung's H-Arx hypervisor architecture for Exynos devices, which has had a lot of changes in recent years and pretty interesting design. Hope you all enjoy :) dayzerosec.com/blog/2025/03/…

Reversing Samsung's H-Arx Hypervisor Framework - Part 1

In many ways, mobile devices lead the security industry when it comes to defense-in-depth and mitigation. Over the years, it has been proven time and again that the kernel cannot be trusted to be...

There are a few ways on PS5 to defeat HV. One of methods that I've found was related to APIC: struct apic_ops is located in RW segment of kernel data. With KRW you can overwrite a function pointer inside it like xapic_mode and get into ROP, for example (just need to bypass CFI).

the most annoying thing about the jailbreak beggars isn’t even the brazen entitlement. it’s refusing to understand that the time/effort needed to exploit something is not linear and often totally unpredictable. “Eta wen???” despite this being explained to them hundreds of times
