An issue was discovered in the Linux kernel before 5.2.8. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/helper.c (motu_microbookii) driver.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
