They fixed a vulnerability in the semaphore mechanism but forgot the message queues and shared memory mechanisms. Analyzing public fixed vulnerabilities can help you learn about the inner details of the affected subsystem and sometimes even lead to new vulnerabilities being discovered.

An example I often mention is the issues below. The three mechanisms (message queues, semaphores, and shared memory) of the IPC subsystem in the Linux kernel share code. Knowing this, if there's a vulnerability affecting one mechanism, it's worth checking if it also affects the other mechanisms.

Attendees at my trainings or people interested in vulnerability research complain to me from time to time about how hard it is to find vulnerabilities. Yes, it's hard and requires expertise most of the time, but there are also good things publicly available.

We (@alleleintel.com) are slowly updating our research page. It should include some LPE exploits we wrote and vulnerabilities we found in the past.

I came across this presentation while checking if the issue highlighted below had a CVE assigned. We reported it to SSD in 2021. It was still affecting a version of Red Hat Enterprise Linux and some Samsung devices at the time we reported it.

I also liked learning the term "public 0days".
