<p>>For me a number station needs sends a message to be a number station, not a key.<p>We don't know that it's a key that's being sent. For all we know, it could be just random data. Obviously it's most likely not random data, but ciphertext. Either way, we have no idea what the message is.</p>

<p>Which just reinforces my point. The patch was available, therefore, where the exploit lies was also available.<p>Linux kernel is one of the most audited open-source projects ever. I guarantee you that someone did reverse the patch.<p>> but forgot to tell the distros<p>Probably an oversight, but irrelevant. The bug was in the linux kernel. It's insane to suggest that they should have notified everyone shipping the linux kernel.</p>

<p>Not true, if there’s any evidence of the exploit being used in the wild, it’s much more responsible to release immediately.<p>Considering that the patches have been available for a while, someone surely reversed what they were for and was actually exploiting this in the wild.<p>In the age of AI, I’d argue that “responsible disclosure” is dead. Arguably even in closed source projects. Just ask Claude to do a diff between the previous version and to see whether anything fixed in there could have had security implications.<p>We’re not there yet, but very soon the only way to responsibly disclose a vulnerability will be immediately.</p>

All you need is a bootchain exploit. However unlike in the old jailbreaking days when people found and publicized them for fun, these days they are worth millions.
