Detailsinfo

A vulnerability was found in Linux Kernel (Operating System) (unknown version). It has been declared as problematic. This vulnerability affects the function snd_rawmidi_input_params of the file rawmidi.c of the component MIDI Kernel Driver. The manipulation with an unknown input leads to a double free vulnerability. The CWE definition for the vulnerability is CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 08/21/2018. The weakness was published 08/21/2018 with Zero Day Initiative as confirmed bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability was named CVE-2018-10902 since 05/09/2018. The attack needs to be approached locally. The requirement for exploitation is a single authentication. There are known technical details, but no exploit is available.
