Perhaps it's a similar situation for Ladybird.
>Memory safety remains a relevant problem: all Chrome exploits caught in the wild in the last three years (2021 – 2023) started out with a memory corruption vulnerability in a Chrome renderer process that was exploited for remote code execution (RCE). Of these, 60% were vulnerabilities in V8.
> V8 vulnerabilities are rarely "classic" memory corruption bugs (use-after-frees, out-of-bounds accesses, etc.) but instead subtle logic issues which can in turn be exploited to corrupt memory. As such, existing memory safety solutions are, for the most part, not applicable to V8. In particular, neither switching to a memory safe language, such as Rust, nor using current or future hardware memory safety features, such as memory tagging, can help with the security challenges faced by V8 today.
