CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 0CVE-2018-10902 – Linux Kernel MIDI Race Condition Privilege Escalation Vulnerability
https://notcve.org/view.php?id=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 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. Se ha detectado que el controlador del kernel midi raw no protege contra el acceso concurrente, lo que conduce a un doble realloc (doble liberación) en snd_rawmidi_input_params() y snd_rawmidi_output_status(), que son parte del manipulador snd_rawmidi_ioctl() en el archivo rawmidi.c. Un atacante local malicioso podría utilizarlo para escalar privilegios. This vulnerability allows local attackers to escalate privileges on vulnerable installations of Linux Kernel. • http://www.securityfocus.com/bid/105119 http://www.securitytracker.com/id/1041529 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2019:0415 https://access.redhat.com/errata/RHSA-2019:0641 https://access.redhat.com/errata/RHSA-2019:3217 https://access.redhat.com/errata/RHSA-2019:3967 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10902 https://git.kernel.org/pub/scm/linux/k • CWE-415: Double Free CWE-416: Use After Free •
