I will disclose three Local Privilege Escalations (two of those are targeting a specific user, the third one is LPE from any user to root which is considered a critical vuln) and one Information Disclosure bug (Non-root user can know if a directory exist or no anywhere in the fs)

I've released a beta version of #pawnyable, a website to learn advanced binary exploitation🐺🐱🐰🐼 Currently only the Linux Kernel chapter is about 90% complete😖 Other chapters and multilingual support are TODO😇 pawnyable.cafe/

New blog post on our recent discovered vulnerability: Linux kernel io_uring module privilege escalation exploit dawnslab.jd.com/linux-5.19-r…

linux内核io_uring模块pbuf_ring漏洞与提权0day

本实验室使用syzkaller对linux-5.19-rc2版本的io_uring模块进行fuzz时, 在io_register_pbuf_ring()函数中发现了了一枚由于错误的异常处理导致的UAF漏洞, 通过slab跳跃与kernel unlink attack等技巧, 本文较为简单的堆环境下成功实现了提权. 但是目前该漏洞已经在5.19-rc8中被修复, 因此决定将该0day漏洞发现的过程与

One of the reasons I stopped using Firefox is because of that folder it creates in ~/Downloads. Pretty annoying for me.

First part of how we exploited the NetUSB kernel module on TP-Link Archer C7 AC1750 and Netgear R6700 routers. This part focuses on setting up an environment to load and debug the module using Buildroot and QEMU. blog.security.sea.com/posts/…
