CVE-2026-43312 Details
Description
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.
A vulnerability exists in the Linux kernel's handling of the OV5647 camera sensor I2C subdevice controls. The issue arises because the control initialization function is called before the subdevice data is properly set up, creating a risk of segmentation fault. This vulnerability affects the stable version of the Linux kernel.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
