CVE-2026-43312

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.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: media: i2c: ov5647: Inicializar subdev antes de los controles En ov5647_init_controls() llamamos a v4l2_get_subdevdata, pero es inicializado por v4l2_i2c_subdev_init() en la sonda, lo cual ocurre actualmente después de init_controls(). Esto puede resultar en un segfault si se alcanza la condición de error, y tratamos de acceder a i2c_client, así que se corrige el orden.
