That New SWAPGS Spectre Flaw Was Already Patched

Source: Phoronix That New SWAPGS Spectre Flaw Was Already Patched

Windows 10 Was Done Last Month; Linux Yesterday

We only found out about the SWAPGS variant of Spectre V1 which affects Intel processors yesterday, but apparently Microsoft quietly pushed a Windows 10 patch for it last month.  The reason for the delay was that there was no mitigation for Linux machines until yesterday, but now it is here and of course Phoronix has already tested its impact on performance.  You are unlikely to be spied upon with this vulnerability as there are much easier ways to infect your machine and connection.

Check out more information, as well as appreciate the creator of the art work above over at Lansweeper.

As to the performance, thankfully it has a minimal effect on your performance.

: Yesterday the SWAPGS vulnerability was made public as a new variant of Spectre V1 that affects all operating systems and is believed to affect only Intel CPUs. The SWAPGS discovery by Bitdefender was quietly mitigated by Microsoft for Windows 10 last month while yesterday the patches were posted for the mainline Linux kernel as the Grand Schemozzle.
