Linux 4.9.100, Linux 4.16.9 Bring More Spectre V1 Safeguards
Greg Kroah-Hartman has today released his latest slew of stable kernel release updates.
Out today are Linux 3.18.109, Linux 4.4.132, Linux 4.9.100, Linux 4.14.41, and Linux 4.16.9.
The fixes in these stable kernel updates aren't too notable. What is common to the 4.x updates though and representing a handful of the changes are more Spectre Variant One safeguards with various arrays in the kernel. It's the stable backporting of these recent Spectre V1 fixes that days ago entered the mainline Linux 4.17 kernel. These possible safeguards for a Spectre V1 style exploit were uncovered via the Smatch static analysis tool.
