✅ 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: To mitigate this issue, prevent the `vmw_pvrdma` kernel module from loading. Create a file named `/etc/modprobe.d/disable-vmw_pvrdma.conf` with the following content: `install vmw_pvrdma /bin/true`. A system reboot is required for this change to take effect. Disabling this module may impact functionality if VMware paravirtual RDMA devices are actively used.
