Recompiling is unlikely to be a catch-all solution for a recently unveiled Intel CPU vulnerability known as TLBleed, the details of which were leaked on Friday, the head of the OpenBSD project Theo de Raadt says.
The details of TLBleed, which gets its name from the fact that the flaw targets the translation lookaside buffer, a CPU cache, were leaked to the British tech site, The Register; the side-channel vulnerability can be theoretically exploited to extract encryption keys and private information from programs.
Former NSA hacker Jake Williams said on Twitter that a fix would probably need changes to the core operating system and were likely to involve “a ton of work to mitigate (mostly app recompile)”.
This is coming from a former hacker that’s not good.
