I don't know how to mitigate
iTLB multihit vulnerability.
/sys/devices/system/cpu/vulnerabilities/itlb_multihit | KVM: Vulnerable
Found this: iTLB multihit, But i have no access to the host machine where the VM is hosted. Is it possible to fix or mitigate this vulnerability from the guest operating system ?
System specification: Ubuntu Server 20.04 LTS Kernel: 5.4.0-125-generic
I was trying to modify
GRUB_CMDLINE_LINUX_DEFAULT="maybe-ubiquity mitigations=on" and append
mitigations=on but it doesn't provide any result.
