A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl()
function, where it can be used to enable indirect branch speculation after
it has been disabled. This call incorrectly reports it as being ‘force
disabled’ when it is not and opens the system to Spectre v2 attacks. The
highest threat from this vulnerability is to confidentiality.
