Description

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

media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings

When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run sensor->adev is not set yet.

So if either of the dev_warn() calls about unknown values are hit this will lead to a NULL pointer deref.

Set sensor->adev earlier, with a borrowed ref to avoid making unrolling on errors harder, to fix this.

Mitigation

No mitigation is specified in collected source.
