📋 Description
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: ffs: fix mm lifetime handling
io_data stores a pointer to the submitting task's mm_struct, but does not currently hold a reference to it while async requests are pending.
This can result in a use-after-free if the task exits before completion handling finishes.
Take a reference with mmgrab() when queuing the read request and release it with mmdrop() on request completion.
