Attacks have already been demonstrated, pulling secrets out of kernel space with meltdown and http headers/passwords out of a browser with spectre. Javascript PoCs are already in existence, and we can expect them to find their way into adware-based malware within a week or two. Also, I'd be willing to bet you a year's rent that certain three-letter organizations have known about and used this for some time. > So what is this, really?, it's a market exploit opportunity for AMD. Don't bet on it. There's reports of AMD vulnerabilities, also for ARM. I doubt any major architecture is going to make it out unscathed. (But if one does, my money's on Power) _______________________________________________ freebsd-arch@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arch To unsubscribe, send any mail to "freebsd-arch-unsubscribe@freebsd.org"
