What is CVE-2023-53336?
CVE-2023-53336 is a medium-severity vulnerability in Linux kernel, published on 17 Sep 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-476
