Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings<br /> <br /> When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run<br /> sensor-&gt;adev is not set yet.<br /> <br /> So if either of the dev_warn() calls about unknown values are hit this<br /> will lead to a NULL pointer deref.<br /> <br /> Set sensor-&gt;adev earlier, with a borrowed ref to avoid making unrolling<br /> on errors harder, to fix this.
