Vulnerability details
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists due to an error in the qmi_wwan_bind function in drivers/net/usb/qmi_wwan.c in the Linux kernel. A local attacker can supply a specially crafted USB device, trigger divide-by-zero error and cause the system to crash.
Successful exploitation of the vulnerability results in denial of service.
