Last modified

CVE-2018-10902 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.52% chance of exploitation in the next 30 days.
