✅ 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: This flaw can be mitigated by preventing the affected Netronome Flow Processor (NFP) kernel module from loading during the boot time; ensure the module is added to the blacklist file. ~~~ Refer: How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~ Workaround: To mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the vmwgfx kernel module. For instructions relating to blacklisting a kernel module, please see https://access.redhat.com/solutions/41278. Workaround: This flaw can be mitigated by preventing the affected slip driver from loading during the boot time, and ensuring the module is added to the blacklist file. ~~~ Refer: How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~ 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. Workaround: Mitigation for this issue is to skip loading the affected module "netfilter" onto the system till we have a fix available, this can be done by a blacklist mechanism, this will ensure the driver is not loaded at the boot time. ~~~ How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~ Workaround: To mitigate this issue, prevent the tun module 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 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. Workaround: To mitigate this issue, prevent the module sch_hfsc from being loaded by blacklisting the module to prevent it from loading automatically. ~~~ https://access.redhat.com/solutions/41278 ~~~ Workaround: This flaw can be mitigated by turning off 3D acceleration in VMware (if possible) or preventing the affected `vmwgfx` kernel module from being loaded. For instructions on how to blacklist a kernel module, please see https://access.redhat.com/solutions/41278. Workaround: Mitigation for this issue is to skip loading the affected module "fbcon" onto the system until we have a fix available. This can be done by a blacklist mechanism and will ensure the driver is not loaded at boot time. ~~~ How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~ Workaround: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
