What are Solana weaknesses?

I'm curious, could you elaborate on the weaknesses of Solana? As a blockchain platform, it's often touted for its high scalability and speed, but I'm sure there are some drawbacks that might not be as well-known. For instance, how does it fare in terms of security? Are there any notable incidents of hacks or vulnerabilities that have been reported? Additionally, how does its decentralization compare to other major blockchains? Are there any concerns about its centralization tendencies? I'd love to hear your thoughts on these matters.
