Google makes some changes to their kCTF competition, and a few kernel bugs shake out of the LogMeIn and wlan VFS drivers.

Libfuzzer goes into maintenance-only mode and syslog vulnerabilities plague some vendors in this week's episode.
This week's binary episode features a range of topics from discussion on Pwn2Own's first automotive competition to an insane bug that broke ASLR on various Linux systems. At the lower level, we also have some bugs in UEFI, including one that can be used to bypass Windows Hypervisor Code Integrity mitigation.
A bit of a game special this week, with a Counter-Strike: Global Offensive vulnerability and an exploit for Factorio. We also have a Linux kernel bug and a Chromecast secure-boot bypass with some hardware hacking mixed in.
This week's highly technical episode has discussion around the exploitation of a libwebp vulnerability we covered previously, memory tagging (MTE) implementation with common allocators, and an insane iPhone exploit chain that targeted researchers.
A Samsung special this week, starting off with two Samsung specific vulnerabilities, one in the baseband chip for code execution. And a stack based overflow in the RILD service handler parsing IPC calls from the baseband chip for a denial of service. Lastly a Mali GPU driver use-after-free.
This week kicks off with a a V8 misoptimization leading to out-of-bounds access, an unprotected MSR in Microsoft's Hypervisor allowing corruption of Hypervisor code. We also take a quick look at a 2021 CVE with an integer underflow leading to an overflow in the Windows Kernel low-fragmentation heap, and finally an interesting information leak due to the kernel not clearing a sensitive register.
Last week we brought you several Windows bugs, this week we are talking Linux kernel vulnerabilities and exploitation. We start off looking at a weird but cool CPU bug, Reptar, then we get into nftables, io_uring, and talk about a newer mitigations hitting Linux 6.6 that randomizes the caches allocations end up in.
We've got a few Windows bugs this week, but first a fun off-by-one null-byte write. Then we jump into a containerized registry escape, a browser escape with a very simple bug buried deep in the browser, and a kernel bug.
