Cette recommandation ne peut pas être vérifiée automatiquement. Une analyse la liste avec ces instructions lorsque vous passez --include-manual.

View CPU mitigations: $ ls /sys/devices/system/cpu/vulnerabilities Output may resemble the following: "Not affected" CPU is not affected by the vulnerability "Vulnerable" CPU is affected and no mitigation in effect "Mitigation: $M" CPU is affected and mitigation $M is in effect

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure
