speculative execution's side effects left in level 1 cache to infer the
victim's data.
Yet another variant 2 attack vector is for the attacker to poison the
Branch History Buffer (BHB) to speculatively steer an indirect branch
to a specific Branch Target Buffer (BTB) entry, even if the entry isn't
associated with the source address of the indirect branch. Specifically,
the BHB might be shared across privilege levels even in the presence of
Enhanced IBRS.
Currently the only known real-world BHB attack vector is via
unprivileged eBPF. Therefore, it's highly recommended to not enable
unprivileged eBPF, especially when eIBRS is used (without retpolines).
For a full mitigation against BHB attacks, it's recommended to use
retpolines (or eIBRS combined with retpolines).
