CVE-2026-43312 PUBLISHED

media: i2c: ov5647: Initialize subdev before controls

Assigner: Linux
Reserved: 01.05.2026 Published: 08.05.2026 Updated: 08.05.2026

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

media: i2c: ov5647: Initialize subdev before controls

In ov5647_init_controls() we call v4l2_get_subdevdata, but it is initialized by v4l2_i2c_subdev_init() in the probe, which currently happens after init_controls(). This can result in a segfault if the error condition is hit, and we try to access i2c_client, so fix the order.
