In the Linux kernel, the following vulnerability has been resolved:
i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request
Bus cleanup path in DMA mode may trigger a RINGOPSTAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hcidmairqhandler() if it gets to run after the iodata pointer is set to NULL in hcidmacleanup().
Prevent this my masking the ring interrupts before ring stop request.
