Thanks to recent work in Chrome and Emscripten, you can now use up to 4GB of memory in WebAssembly applications. That’s up from the previous limit of 2GB. It might seem odd that there was ever a limit - after all, no work was needed to allow people to use 512MB or 1GB of memory! - but it turns out that there are some…
When a critical Linux kernel privilege escalation was publicly disclosed, Cloudflare's security and engineering teams detected, investigated, and mitigated the threat across our global fleet, confirming zero customer impact and no malicious exploitation.

With our research, however, we have built a tool that automatically generates them with surprising ease. We explain how such attacks work, and why our tool, Einstein…

TigerBeetle is a financial transactions database built for correctness. Yet, building a correct system from correct components remains a challenge:
Huawei has seemingly stepped its foot into the kernel self-protection game with the release of HKSP. Absent any threat model and riddled with weaknesses, it also introduces a trivially exploitable local root vulnerability due to a complete lack of defensive programming.
