Is there any way to configure a system to allow non-root users access to dmidecode?

Solution Verified - Updated -


  • On a stock RHEL system, running dmidecode as a non-root user returns a "/dev/mem: Permission denied" error. Opening up permissions on /dev/mem (via chmod or setfacl) doesn't allow non-root users to run dmidecode; instead, it changes the above error to "/dev/mem: Operation not permitted". Why? Is there any way around this?
