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.

Affected products

• Linux kernel: from 6.18 before 6.18.17; from 6.19 before 6.19.6 — fixed in 6.18.17, 6.19.6

How to fix
