CVE-2018-10902

It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in sndrawmidiinputparams() and sndrawmidioutputstatus() which are part of sndrawmidiioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
