Description OSIDB Bzimport 2025-12-24 14:07:37 UTC 
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.
