The mitigations for Spectre-BHB are only applied when an exception is taken from user-space. The mitigation status is reported via the spectre_v2 sysfs vulnerabilities file. When unprivileged eBPF is enabled the mitigation in the exception vectors can be avoided by an eBPF program. When unprivileged eBPF is enabled, print a warning and report vulnerable via the sysfs vulnerabilities file.
