CVE-2018-10902 (opens in a new tab)How to fix?
Upgrade SLES:15.0 kernel-macros to version 4.12.14-25.16.1 or higher.

See How to fix? for SLES:15.0 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.
