I found a linux kernel 0 day and get root shell : ). This is the first time I successfully achieved LPE. I reported it to the Linux Kernel Security Team today. When it has been patched, I’ll publish the full research record on my blog.
Here goes nginx-quicburst (CVE-2026-42530), a new RCE in Nginx discovered by our security agent VEGA and demonstrated by Nebula Security.
This is only the third NGINX vulnerability since 2014 to receive NGINX’s “major” severity rating. If you use Nginx 1.31 with QUIC enabled, we recommend upgrading to the latest version.
This bug has been patched in the latest Nginx release. We will publish the technical writeup, including the ASLR bypass, on July 18 together with the previous nginx-poolslip writeup.
And this one is human insight w/ LLM-assisted research. Took about one week to finish everything. The AI really rescued me from a lot of tedious work
— excluding the part where it changed the Domain Admin password, locked me out, and claimed it got RCE 🤦
