Vulnerable: No microcode

The intel paper:

Tried package microcode_ctl to update the microcode.
currently installed microcode_ctl package is

sudo dnf list --installed | grep microcode
microcode_ctl.x86_64                                 2:2.1-65.fc41                       fedora

[@fedora ~]$ grep 'stepping\|model\|microcode\|family' /proc/cpuinfo
model		: 78
CPU family    : 6
stepping	: 3
microcode	: 0xf0
[@fedora ~]$

Steps Followed are as below from:

mentioned as Early OS Microcode Update

step 1: Downloaded the intel microcode git from

step 2: replace the new microcode file with the existing one

step 3: dracut -f "initramfs-$(uname -r).img" $(uname -r)

step 4: dracut -f -vvv

step 5: systemctl reboot

This is not working,

please help me to mitigate the microcode update
