sshhole bug analysis: MUSL-based systems hit hard, up to 500M OpenWRT routers were at risk
esrtweet · x · 2026-11-06
esrtweet shares an early analysis of the newly disclosed sshhole bug: it is severely dangerous for Alpine Linux and other systems using MUSL as their C library. The worst-case scenario could have opened a root-access hole in OpenWRT routers — perhaps 30% of them, roughly 100-500M units worldwide — which the author believes was narrowly avoided.
Findings are unconfirmed because ChatGPT refused to help with the security analysis; the author is asking credentialed infosec researchers to verify. He first learned of it from a friend's urgent warning to unplug OpenWRT routers immediately.
