Day[0] [binary] A Windows UAF, Branch Prediction Bugs, and an io_uring Exploit
Links and vulnerability summaries for this episode are available at: https://dayzerosec.com/podcast/a-windows-uaf-branch-prediction-bugs-and-an-io-uring-exploit.html
This time as we get side tracked with a couple discussions, first about security through obscurity, secondly about the nvidia leaks. We also have our usual mix of vulnerabilities this week, a cool exploit in the Linux kernel, a use-after-free in Windows Common Logging File System, and some speculative execution issues.
