CVE-2018-10902

kernel: MIDI driver race condition leads to a double-free

Published Aug 21, 2018 CVSS 3.0 · 7.8 High EPSS < 1% KEV · Not listed
Description
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.
