CVE-2022-50741

Summary

In the Linux kernel, the following vulnerability has been resolved:

media: imx-jpeg: Disable useless interrupt to avoid kernel panic

There is a hardware bug that the interrupt STMBUF_HALF may be triggered after or when disable interrupt. It may led to unexpected kernel panic. And interrupt STMBUF_HALF and STMBUF_RTND have no other effect. So disable them and the unused interrupts.

meanwhile clear the interrupt status when disable interrupt.
