    CVE-2018-10902

    Published: 21 Aug 2018Last Modified: 15 Mar 2026

    Summary:

    Details: 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.
