CVE-2023-53693

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

USB: gadget: Fix the memory leak in raw_gadget driver

Currently, increasing raw_dev->count happens before invoke the raw_queue_event(), if the raw_queue_event() return error, invoke raw_release() will not trigger the dev_free() to be called.

This commit therefore invoke kref_get() under the condition that raw_queue_event() return success.
