How to fix?

There is no fixed version for Centos:7 kernel-rt-trace-kvm.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace-kvm package and not the kernel-rt-trace-kvm package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call.
