a095127f014bb4ceab1d6e252b903fe7FreeBSD Security Advisory - On certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods. This issue affects bhyve on FreeBSD/amd64 systems. An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.
