HIGH 7.8 NVD
CVE-2026-90045
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
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.
