I have had this issue for probably at least a week. I do not see any notes about it on http://forums.dds6qkxpwdeubwucdiaord2xgbbeyds25rbsgr73tbfpqpt4a6vjwsyd.onion/t/whonix-17-2-0-7-point-release/20168 , but I assume it was caused by the point release.
Whenever I start up whonix gateway or whonix workstation, I get a number of messages on the black screen. One of these messages is the following.
“RETBleed: WARNING: Spectre v2 mitigation leaves CPU vulnerable to RETBleed attacks, data leaks possible!”
Is this intentional? Is it a problem? If so, what should I do about it?
In my attempt to self-support myself, I found [FIXED] Spectre v2 mitigation leaves CPU vulnerable to RETBleed attacks in Ubuntu | GoLinuxCloud on a search engine. It seems to say to either disable the message, disable the retbleed mitigations, or do something else to modify by system using “retpoline”. I do not know what that is, and I want to check with the forum before doing anything to mess up the system. I thought that the correct security decisions were implemented by default, and I do not want to mess up the default configuration without knowing what I am doing.
Is anyone else having this issue? Thank you for your help.
