Out-of-Bounds Write in Linux Kernel (CVE-2017-17558)
Summary
Out-of-bounds write in Linux Kernel (CVE-2017-17558). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.
