- juergbi 9y agoNot everything. In-order CPUs such as Cortex-A7 and Cortex-A53 are not affected. Confirmed by Arm at https://developer.arm.com/support/security-update https://developer.arm.com/support/security-update "all other Arm cores are NOT affected"
- Tloewald 9y agoDoesn’t Spectre just require speculative fetching? In which case in order is not sufficient as to guarantee immunity. It’s Meltdown that relies on out of order execution. https://meltdownattack.com/meltdown.pdf https://meltdownattack.com/meltdown.pdf https://spectreattack.com/spectre.pdf https://spectreattack.com/spectre.pdf
