Subject: [media] st-hva: potential null pointer dereference in hva_hw_its_irq_thread()
Date: Fri, 18 Sep 2020 10:40:02 +0300 [thread overview]
Message-ID: <688931600414652@mail.yandex.ru> (raw)
If ctx_id >= HVA_MAX_INSTANCES in hva_hw_its_irq_thread(), it dereferences
ctx that is initialized to NULL.
I can not provide the patch since I do not know the logic of the driver
and I have not a capability to test it.
Found by Linux Driver Verification project (linuxtesting.org).
