NE_ERR_INVALID_ENCLAVE_CID(9)

💅 NE_ERR_INVALID_ENCLAVE_CID(9) 💅

okay bestie, welcome to the Kernel API Manual — yes you read that right, we're in kernel land today and honestly? it's giving main character energy. ✨

🎀 NAME 🎀

NE_ERR_INVALID_ENCLAVE_CID — the error that says "bestie, that CID is not it."

So like, the enclave CID you handed over is invalid, and there are exactly two reasons it could be clowning you: it's a well-known value, or it's the CID of the parent / primary VM. That's the whole vibe check, and it failed. 😭

🦋 SYNOPSIS 🦋

NE_ERR_INVALID_ENCLAVE_CID

that's it. that's the whole synopsis. short, iconic, no notes. 👑

🌈 SEE ALSO 🌈

okay this list is long, but every single one is important so we're not skipping a single crumb, periodt. 💅

like I said — all of them. we ate and left zero crumbs. 🍓

lowkey a whole study guide at this point, but that's the energy. go read the other pages, they're all besties of this one. 🫶

and that's a wrap, bestie! this page lives in ./include/uapi/linux, straight from the October 2026 release, and it's called NE_ERR_INVALID_ENCLAVE_CID(9) — no cap, go touch some VMs. 💜✨
