✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To reduce the risk associated with this vulnerability, restrict the use of USB passthrough in virtualized environments. Administrators should ensure that only trusted USB devices are allowed to be passed through to virtual machines. Disabling USB passthrough when not strictly necessary can prevent a local attacker from exploiting this flaw to cause a denial of service.
