- ChuckNorris89 7y agoLike your PC and smartphone it is vulnerable in theory without software mitigations but have there been any documented practical Spectre attacks in the wild? AFAIK Spectre implementations have been limited to security researchers in universities ATM. So I'll ask, is it worth worrying about this for you? In terms of vulnerabilities there are lower hanging fruits.
- steve_musk 7y ago>Like your PC and smartphone This isn’t necessarily true for your smartphone, because some ARM CPUs don’t do the speculative execution that Spectre/Meltdown exploit. For example, CPU in the raspberry pi 3 didn’t have these vulnerabilities which I assume is why the parent was asking this question.
- ChuckNorris89 7y agoMost modern smartphones have Arm based chips with speculative execution which are vulnerable without software patches.
- monocasa 7y agoIt is.
- novaRom 7y agoYes, because Pi4 has Cortex A72 wich is vulnerable to Spectre Source: https://www.androidauthority.com/meltdown-spectre-kpti-827527/ https://www.androidauthority.com/meltdown-spectre-kpti-82752...
