Intel has announced that the fix is out for its latest chips affected by Spectre, the memory-leakage flaw affecting practically all computing hardware. The patch is for the Skylake generation (late 2015) and newer, though most users will still have to wait for the code to be implemented by whoever manufactured their computer (specifically, their motherboard).

The various problems presented in January by security researchers have to be addressed by a mix of fixes at the application, OS, kernel and microarchitecture level. This patch is the latter, and it replaces an earlier one that was found to be unstable.
