Description

A vulnerability was found in the Linux kernel's CDC WDM driver, where excessive logging in the interrupt-URB completion callback could lead to CPU lockups, which occurs when the driver rapidly resubmits interrupt URBs after receiving a -EPROTO status, causing a backlog of error messages that ultimately results in a soft lockup.
