Say hello to Downfall, another data-leaking security hole in several years of Intel chips
Hidden Linux kernel security fixes spotted before release – by using developer chatter as a side channel
"The Gather instruction helps the software access scattered data in memory quickly, which is crucial for high-performance computing workloads performing data encoding and processing," explained Moghimi and Ormandy."Downfall shows that this instruction forwards stale data from the internal physical hardware registers to succeeding instructions."
The x86 giant, meanwhile, sought to downplay the security weakness, saying the Googlers exploited the shortcoming “within the controlled conditions of a research environment.""While this attack would be very complex to pull off outside of such controlled conditions, affected platforms have an available mitigation via a microcode update," an Intel spokesperson told us today.
