Notes

tyhicks

Variant 2, aka "Spectre"

mdeslaur

intel-microcode updates were reverted in usn-3531-2

tyhicks

The break-fix lines for this CVE are not complete since a large number of patches are required to mitigate this issue. The commit(s) listed are chosen as placeholders for automated CVE triage purposes.

leosilva

Due to the lack of recent CPU models in qemu and the lack of microcode early-loading support in the precise kernel, we do not plan on backporting support for the new flag to QEMU and libvirt at this time.
