gobee

gobee Write your BPF programs in Go, not C. gobee transpiles a strict subset of Go into BPF C, generates typed Go bindings for the userspace side, and gates loads against the running kernel. The Go ecosystem has solid userspace tooling for BPF. The kernel side has always ended with "now write you...

CVE-2021-29155

This is the Proof Of Concept code for CVE-2021-29155. The range tracking system for pointer arithmetic in the speculative domain was insufficient. It was possible to extract kernel data via a sidechannel. This is a proof of concept you can read up to 0x5fff bytes out of bounds from the last eleme...
