A Deep Dive into V8 Sandbox Escape Technique Used in In-The-Wild Exploit
We were analyzing an in-the-wild V8 vulnerability, CVE-2023–2033. Once we exploited the bug, it was not difficult to get typical exploit primitives such as addrof, read and write in V8 heap. The problem is that we need to escape the V8 sandbox in order to get code execution.

Exploiting an io_uring Vulnerability in Ubuntu

This post discusses a use-after-free vulnerability, CVE-2024-0582, in io_uring in the Linux kernel. Despite the vulnerability being patched in the stable kernel in December 2023, it wasn’t ported to Ubuntu kernels for over two months, making it an easy 0day vector in Ubuntu during that time.
