Description OSIDB Bzimport 2025-06-18 12:04:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

gadgetfs: ep_io - wait until IRQ finishes

after usb_ep_queue() if wait_for_completion_interruptible() is
interrupted we need to wait until IRQ gets finished.

Otherwise complete() from epio_complete() can corrupt stack.
