Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1501880] Statement: This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5,6, 7, realtime and MRG-2. Red Hat Enterprise Linux 5 has transitioned to Production phase 3. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. The official life cycle policy can be reviewed here: http://redhat.com/rhel/lifecycle Future Linux kernel updates for the respective releases may address this issue. Mitigation: It is possible to prevent the affected code from being loaded by blacklisting the kernel module snd_seq. Instructions relating to how to blacklist a kernel module are shown here: https://access.redhat.com/solutions/41278 Alternatively a custom permission set can be created by udev, the correct permissions will depend on your use case. Please contact Red Hat customer support for creating a rule set that can minimize flaw exposure. kernel-4.13.8-300.fc27 has been pushed to the Fedora 27 stable repository. If problems still persist, please make note of it in this bug report. kernel-4.13.8-100.fc25 has been pushed to the Fedora 25 stable repository. If problems still persist, please make note of it in this bug report. kernel-4.13.8-200.fc26 has been pushed to the Fedora 26 stable repository. If problems still persist, please make note of it in this bug report. Got pinged on not making 5.9.z trackers, which are required for els trackers.
