✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Workaround: In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel "USB Video Class module" (uvcvideo) module . For instructions relating to how to blacklist a kernel module refer to: https://access.redhat.com/solutions/41278uvcvideoz Workaround: To mitigate this issue, prevent module sch_hfsc from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
