FreeBSD Security Advisory - FreeBSD-SA-18:07.lazyfpu
Posted Jun 21, 2018
Authored by Julian Stecklina | Site security.freebsd.org

FreeBSD Security Advisory - A subset of Intel processors can allow a local thread to infer data from another thread through a speculative execution side channel when Lazy FPU state restore is used. Any local thread can potentially read FPU state information from other threads running on the host. This could include cryptographic keys when the AES-NI CPU feature is present.
