[binary] Busted Stack Protectors, MTE, and AI Powered Fuzzing

What this episode covers

A binary summer-recap episode, looking at some vulnerabilities and research put out over the summer. Talking about what TPM really offers when it comes to full-disk encryption, some thoughts on AI in the fuzzing loop. Then into some cool bugs, kicking off with some ARM Memory Tagging Extension vulnerabilities, a `-fstack-protector` implementation failure and bypass, and then a look at a Android exploit that was found in-the-wild.
