Aren't at-risk applications notably browsers? And doesn't the branch prediction version require both kernel and bios/uefi updates? Thank you for your support

To be at-risk, the application must have valuable private data, attacker-controlled-data-dependent flow, and timing visible to the attacker. Browser example: auth tokens, js programs, and time apis+visible timing of network requests.
-
The canonical attacks are ones where the attacker-controlled "data" is code that runs in a sandbox/interpreter/jit, but...
-
Soon after Spectre was announced, I speculated (pardon the pun) that it may be possible to exploit via data that nobody thinks of as "code" if there are ways to observe the timing of processing it. Nobody has PoCs for that AFAIK, though.
