Remedy

Disabling unprivileged eBPF effectively mitigates the known attack vectors for exploiting intra-mode branch injections attacks. The default Red Hat Enterprise Linux kernel prevents unprivileged users from being able to use eBPF by the kernel.unprivileged_bpf_disabled sysctl. For the Red Hat Enterprise Linux 7 the eBPF for unprivileged users is always disabled. For the Red Hat Enterprise Linux 8 to confirm the current state, inspect the sysctl with the command: # cat /proc/sys/kernel/unprivileged_bpf_disabled The setting of 1 would mean that unprivileged users can not use eBPF, mitigating the flaw. Continue to enable SMEP and Enhanced IBRS. This is the default setting on eligible CPUs.

Remedy

To mitigate the primary known attack vector, disable unprivileged eBPF: $ sudo sysctl kernel.unprivileged_bpf_disabled=1 or $ sudo sysctl kernel.unprivileged_bpf_disabled=2
