[ Upstream commit dc6306ad5b0dda040baf1fde3cfd458e6abfc4da ]
The SRSO default safe-ret mitigation is reported as "mitigated" even if
microcode hasn't been updated. That's wrong because userspace may still
be vulnerable to SRSO attacks due to IBPB not flushing branch type
predictions.
Report the safe-ret + !microcode case as vulnerable.
Also report the microcode-only case as vulnerable as it leaves the
kernel open to attacks.
Fixes:
