CVE-2018-10902 (opens in a new tab)How to fix?
Upgrade Oracle:7 kernel-uek-devel to version 0:3.8.13-118.29.1.el7uek or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-devel package and not the kernel-uek-devel package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
