[binary] Hypervisor Bugs and a FAR-out iOS bug

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.
