The Halo 2 HD blog post is out! This covers everything I did to get the game rendering in HD resolutions from patching the rendering engine and memory allocators, to hot patching the Xbox OS, and overclocking the GPU and getting perf measurements icode4.coffee/?p=738

Nice! gabe_k of exploits.forsale takes full advantage of first #Pwn2Own by demonstrating an LPE on #Windows 11. He's off to the disclosure room to provide all the details. #P2OVancouver

@cajuinaoverflow Se voce tem w^x/dep/nx ou sei la, praticamente a stack nao é RWX voce vai precisar fazer um ROP/JOP ou algo do tipo pra code exec, mas tbm depende do que vc ta mexendo (assumindo q vc n tem stack canaries pra lidar tbm)

@SebAaltonen @SunlessSolaire It does remind me of the examples from learnopengl in the PBR->Light section. Cool stuff anyway

@SunlessSolaire I would personally also copy these formulas directly from respective papers. I would put a comment above each function with a paper link to make it easier to read the source paper later. No idea if GPT4 copied the main function directly from somewhere. Mine would look similar.

I asked GPT4 to write me a PBR shader in GLSL:

@gabe_k Always happy to follow your content, 10/10

Towards the next generation of XNU memory safety: kalloc_type security.apple.com/blog/towards-t… I’m so happy that the team finally gets to share the details of this huge effort. And I’m so proud I had the chance to work on it in the past couple of years. :)

@Grimdoomer Gibe me :v

Anyone have any interest in these? I’m gonna upload ISOs to archive.org but idk what to do with the disks
