Out-of-bounds write in Linux kernel - CVE-2017-17558

Vulnerability identifier: #VU9771

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2017-17558

CWE-ID: CWE-787

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to the usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel does not consider the maximum number of configurations and interfaces before attempting to release resources. A local attacker can supply specially crafted USB device, trigger out-of-bounds write access and cause the system to crash.

Successful exploitation of the vulnerability results in denial of service.
