Official description

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

media: iris: Add missing platform data entries for SM8750

Two platform-data fields for SM8750 were missed:

- get_vpu_buffer_size = iris_vpu33_buf_size Without this, the driver fails to allocate the required internal buffers, leading to basic decode/encode failures during session bring-up.

- max_core_mbps = ((7680 * 4320) / 256) * 60 Without this capability exposed, capability checks are incomplete and v4l2-compliance for encoder fails.
