Published my technical write-up on a vulnerability I discovered in Windows usbprint.sys. The issue was reported to MSRC, but Microsoft decided not to issue a fix. I’ve documented the technical details and PoC in the blog. Blog writeup:

which model did you use to find this?

Initially found via manual audit and then I throw the rest of analysis to Opus 4.6. It does the job from verifying the bug to PoC.

Why won't they fix? Don't they know how?

I have no idea 😅

I'd call this more than moderate. A deterministic kernel crash over TCP from a Linux box gets moderate severity, no CVE, no bounty. The servicing bar only moves for RCE.

Its their decision. We can’t do much from our side 😅

I'd still call a remote kernel crash over TCP more than moderate. MSRC's bar is RCE-or-bust now. Your writeup proves the real impact.

A quick writeup on potential security issue of Windows LNK that I reported to MSRC last month. They decided to not fix due to relying on MOTW. In the blog I included the proof of concept. All you have to do is to Right-Click and get Info Disclosure :)

Here's a video PoC for Azure Entra ID SignIn Log Bypass in action. I had to make it to help MSRC replicate it (lol). You'll see how simple this bypass was. No worries admins, Microsoft says that it was only a "Moderate" issue.

Google is now claiming their maps hiding the destruction from the Palisades Fire is just a “technical issue” Anyone else find it funny that every time there’s a glitch, or technical issue it seems to always be in favor of the left🤔

A bizarre technical “glitch” just hit CNN — right as Stephen Miller was getting to the heart of a district judge ruling on National Guard deployment. Miller was cut off mid-sentence, unable to finish his explanation. The host, Boris Sanchez, eventually cut in: “Stephen, Stephen, can you hear me?” “Stephen, I apologize. It seems like we’re having a technical issue. We’ll try to fix that and get back to you after a quick break.”
