Since when does "memory corruption" = "RCE"? Last week I found and reproduced a memory corruption (a use-after-free) in PHP's runtime after running an on-premise agent for just 30 minutes. There's nothing about it on the internet. Should I write a blog post about a scary new vulnerability? :)

I don't know the backstory here, but there's a long and colorful history of vendors and other parties guessing that some contrived memory corruption bug isn't exploitable and then being proven wrong, so the industry now more or less defaults to the assumption that it's exploitable.
Let me remind you that in response to the PHP bug, one of the front-page HN posts was a guy saying it's probably not exploitable and another offering Bitcoin to anyone who pops their server... with predictable results.
People can be pretty creative with exploitation primitives, and LLMs now replicate that at a scale. And yep, if you found a use-after-free that can be triggered remotely in PHP under some reasonable assumptions, you should probably treat it as a security bug.
If you can corrupt memory in a controllable way, you can get a computer to do just about anything that process has rights to. Possibly even the kernel, if you can get at some shared memory.
RedHat claims there's a working RCE:
> (...) public research has demonstrated a reliable exploit against a default-configured server with the mod_http2 module enabled. Successful exploitation allows an attacker to execute arbitrary commands, gain full control of the server process, and access or modify sensitive information.

Discovered independently by Anthropic (Oct 26) and Google (Nov 3), so I'm compelled to believe it: https://httpd.apache.org/security/vulnerabilities_24
But maybe someone will post another HN challenge like with the PHP thing?
I was prepared to disagree with you, but I agree: I'd say there's a strong norm of not calling things RCE unless you can actually demonstrate RCE, or at least have a clean pathway to demonstrating it (e.g. a full write-what-where).
It's perfectly sufficient to have a CVE for just memory corruption, so the "RCE" framing here feels overstated. Particularly when an LLM should easily prove RCE out if it is in fact present.
