You might want to change the subject line, some people don't read every message posted and someone with the answer to a rkhunter query may not see your message. I see *old* data about them: https://www.linuxquestions.org/questions/linux-security-4/suspicious-rkhunter-entry-for-dev-shm-lttng-ust-wait-7-1000-ubuntu-18-04-1-a-4175678671/ https://unix.stackexchange.com/questions/227184/what-is-dev-shm-lttng-ust-wait-5-for As a general answer, those (rkhunter) kind of programs are always after-the-fact. Any time there's a change in how a system works, or a new exploit in the wild, they don't know about it until they're updated. And some things, like transient files, mightn't be possible to categorically declare them to always be safe, or risky. In a case like this, I don't necessarily mean a "dnf update" to your install. But probably that the program itself needs a change in how it works. There's every chance that you might have to ask the question directly with rkhunter's support. And they could easily turn around and say it's a unique quirk of Fedora, and they should manage the problem. That's one problem with using protective software like them (rkhunter, ABRT, SELinux troubleshooter, anti-virus, etc). You have to know how to deal with its results to actually be able to use it. When people don't, they go around deleting files they shouldn't, allowing things they shouldn't, or just ignoring all the things they warn about. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
