✅ 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: If ETS (Enhanced Transmission Selection) scheduler not being used, then the mitigation would be to disabled related Kernel module. To mitigate this issue, prevent module sch_ets from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. sch_ets Workaround: To mitigate this issue, prevent InfiniBand modules from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. The names of the modules are: ib_addr, ib_cm, ib_core, ib_mad, ib_sa, ib_ucm, ib_umad, iw_cm. Workaround: To mitigate this issue, prevent module drm from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. Workaround: To mitigate this issue, prevent module vsock from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
