[binary] MTE Debuts, DNS Client Exploits, and iTLB Multihit

Published: Nov. 8, 2023, 7:40 p.m.

As memory tagging (MTE) finally comes to a consumer device, we talk about how it may impact vulnerability research and exploit development going forward. Then we get into a few vulnerabilities including a DNS response parsing bug on the Wii U, an Adobe Acrobat bug that was exploited by a North Korean APT, and a CPU bug (iTLB Multihit).
