Microsoft has a really good article on using a semantic query language to find exploitable DOM XSS findings. Honestly the whole series is recommended, but the DOM XSS one here is particularly good.

Google Project Zero revealed a UAF bug in Android a bit ago, and here is an awesome analysis of how it happened.  Good reading for mobile devs especially, but I certainly learned stuff too.
