Null-dereferences might not be too exploitable on a lot of systems, what about the handling of a null-dereference. We cover a great Project Zero post on the topic, then look at a type confusion in Windows COM, a Nintendo buffer overflow, and several memory corruptions in git, highlighting their unique primitives and potential exploitability.

An Apple-focused episode this week, with a trivial iPod Nano BootRom exploit, and a WebKit Use-after-free. We also have a really cool XNU Virutal Memory bug, strictly a race condition and a logic differential between two alternate paths resulting in bypassing copy-on-write protection. We also handle a few questions from chat, how much reverse engineering is necessary for vuln research, how much programming knowledge is required, and a bit about AI's applicability to reverse engineering.
Just a few issues this week, but some solid exploitation. A Kernel UAF, IoT, and a bhyve escape.
In this episode, we discuss the discovery of a type confusion in Internet Explorer's JScript. We also explore a fun exploit strategy for a low-level memory management bug in the Linux kernel and delve into several issues in Huawei's Secure Monitor that enable code execution in the secure world.
Will AI be your next vuln research assistant? ... Maybe? We also talk about a stack-based overflow in `ping` and a Huawei hypervisor vuln.
The end of kASLR bypasses? Probably just click-bait, but the patch gap is real and we discuss that a bit before getting into a couple AI-based corruptions.
A hardware heavy episode as we talk about two read protection bypasses, Pixel 6 bootloader exploitation and benchmarking fuzzers.
Is the compiler making exploitation easier, these divergent representations seem to do so. We also look at a chrome UAF and a double stack overflow.
A lot of discussion about the OpenSSL vulnerability, fuzzing and exploitation. Then into a RCE in XML Signature verification, and a Samsung exploit chain.
Kicking off the week with a look at Apple's new security blog and the kalloc_type introduced into XNU, then a mix of issues including an overflow in SQLite.
