Super cool potential ASLR leak via dictionary hashing by @tehjh! googleprojectzero.blogspot.com/2025/09/pointe…
Say hello to Eternal Tux🐧, a 0-click RCE exploit against the Linux kernel from KSMBD N-Days (CVE-2023-52440 & CVE-2023-4130) willsroot.io/2025/09/ksmbd-… Cheers to @u1f383 for finding these CVEs + the OffensiveCon talk from gteissier & @laomaiweng for inspiration!
Understanding GPU Architecture from Cornell cvw.cac.cornell.edu/gpu-architectu… During a low-level discussion at a casual meetup, many folks were interested in understanding GPUs more closely. While CPUs optimize for complex control flow (see those big cores + caches), the GPUs maximize…
goo.gle/bigsleep now with even more bugs. Also great to see the first ones getting fixed, including in v8, ANGLE and imagemagick.
How do I know it's plagiarized AI slop that evaded upstream reviewers? The well-written commit message is riddled with basic errors that nobody who actually produced the code through testing it would make: first, it does a setrlimit of RLIMIT_NOFILE that's higher than...

Some personal news: I'm thrilled to be moving back to Project Zero! Specifically I'll be joining the Big Sleep project to find vulnerabilities in JavaScript engines. We've already found and reported our first vulnerability in V8 last week: issuetracker.google.com/issues/4362107…
New from our security teams: Our AI agent Big Sleep helped us detect and foil an imminent exploit. We believe this is a first for an AI agent - definitely not the last - giving cybersecurity defenders new tools to stop threats before they’re widespread.
I wanted to end last year with a vm escape, took me a bit longer but I want to present you my latest public research: A VM escape in Oracle VirtualBox using only one integer overflow bug! This was fixed in April 15 and assigned CVE-2025-30712. github.com/google/securit…
Well. It’s that obvious that forcing Google to sell Chrome would be the greatest harm the gov could do in cybersecurity, without Google’s financial support and its security culture I don’t think any others can do browser security right.
🔨 Posthammer (USENIX Sec '25) brings Rowhammer back in the browser! What if visiting a website was enough to trigger a Rowhammer attack? Posthammer shows how to bring non-uniform Rowhammer patterns into the browser. More information: 📄comsec.ethz.ch/posthammer
a major reason why i use iphone
Excellent blog post by @ VirtualAllocEx on inline assembly, shell coding and direct system calls
Since a lot of you seem to have liked my previous challenge, here's a new one. The goal is, once again, to find a bug and leak the secret. BTW all AI-generated responses failed quite spectacularly last time, so perhaps it's better if you refrain from using it.
CVE-2025-0927 details here! ssd-disclosure.com/ssd-advisory-l…
🔥 HUGE #RomHack2025 updates you need to know this week... James @albinowax Kettle, one of the world’s leading figures in web security research, will open the conference ⤵️ romhack.io #cybersecurity #blackhat #defcon
@X2Dnlz @R3st4rtY0urL1f3 @M_Solidus Using an iPhone is better than using a theoretical incomplete port of GrapheneOS to an insecure device with a bunch of core features missing. It would also be very confusing for users if we had supported devices which aren't secure, lag behind on updates and are missing features.
Beyond using a phone or tablet as a desktop by connecting a display, keyboard, mouse, etc. to the USB-C port, we want to eventually have support for GrapheneOS on laptops. There's currently no laptop close to meeting the hardware requirements we cover at grapheneos.org/faq#future-dev….
You can now jailbreak your AMD CPU! 🔥We've just released a full microcode toolchain, with source code and tutorials. bughunters.google.com/blog/542484235…
