Rust in the Linux kernel: the experiment is over, Rust is here to stay
The bindings-and-abstractions architecture, where Rust already runs (Android, Binder) and lessons from the kernel's first Rust CVE.
Hardening C++ you can't drop yet: libc++ hardening cut Google's segfaults 30%
Bounds checks in the C++ standard library: fast/extensive/debug modes, how to enable them, the rollout path and real numbers from Google.
MiraclePtr: how Chrome blocks use-after-free in C++
BackupRefPtr keeps a hidden reference count, then quarantines and poisons freed memory with dangling pointers. Real costs and lessons for legacy C++.
Rust supply-chain security: cargo-audit, cargo-deny and cargo-vet
Rust is memory-safe, but malicious crates still get in. The RustSec, cargo-deny and cargo-vet toolkit and how to wire it into CI.
Testing unsafe Rust: Miri and cargo-fuzz catch what the compiler can't
Miri detects undefined behaviour while running tests, cargo-fuzz generates crashing inputs. How to put both in CI for unsafe and FFI code.
Why 70% of serious vulnerabilities are C/C++ memory bugs
Data from Microsoft, Chromium and Android, the common memory bugs (buffer overflows, use-after-free…) and why careful coding or sandboxing isn't enough.
How does Rust stop memory bugs? Ownership, borrowing and real Android data
Ownership, borrowing and lifetimes; other safeguards; Android data (~1000× lower memory vulnerability density) and the limits of unsafe Rust.
Moving from C/C++ to Rust: you don't need to rewrite everything
Android's lesson: vulnerabilities cluster in new code, so write new code in Rust; a 4-step roadmap, the CISA/NSA framework, cxx/FFI and AI translation.
