Famed Linux developer Linus Torvalds has some pretty harsh words for Intel on the fiasco over Meltdown and Spectre, the massive security flaws in modern processors that predominantly affect Intel products.
Meltdown and Spectre exploit an architectural flaw with the way processors handle speculative execution, a technique that most modern CPUs use to increase speed. Both classes of vulnerability could expose protected kernel memory, potentially allowing hackers to gain access to the inner workings of any unpatched system or penetrate security measures. The flaw can’t be fixed with a microcode update, meaning that developers for major OSes and platforms have had to devise workarounds that could seriously hurt performance.
