Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access<br /> <br /> When translating source to sink streams in the crossbar subdev, the<br /> driver tries to locate the remote subdev connected to the sink pad. The<br /> remote pad may be NULL, if userspace tries to enable a stream that ends<br /> at an unconnected crossbar sink. When that occurs, the driver<br /> dereferences the NULL pad, leading to a crash.<br /> <br /> Prevent the crash by checking if the pad is NULL before using it, and<br /> return an error if it is.
