Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 4.13.11
Description
The issue is related to the
usbnet generic cdc bind function in the Linux kernel, specifically in the drivers/net/usb/cdc ether.c file. It is caused by a divide-by-zero error. A local attacker can exploit this issue using a specially crafted USB device, potentially leading to a denial of service (system crash) or other unspecified impacts.Recommendations
For Linux kernel versions through 4.13.11, update to a version later than 4.13.11 to resolve the issue. As a temporary workaround, consider restricting the use of USB devices to minimize the risk of exploitation.
