A vulnerabilty was found in the Linux kernels hiddev driver. An attacker with permissions to the USB HID device can call an ioctl with the HIDIOCGUSAGES or HIDIOCSUSAGES command, and passes a report id of HID_REPORT_ID_UNKNOWN range checks that would prevent oversize buffers being copied from userspace to kernel space were bypassed. The kernel would loop on a a value passed by userspace and can copy memory outside of the intended range. This can corrupt memory located after the struct in memory, duplicating the kernel memory or crashing the system Upstream patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93a2001bdfd5376c3dc2158653034c20392d15c5
