Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a null pointer dereference in the mxc isi crossbar xlate streams() function. When translating source to sink streams in the crossbar subdev, the driver tries to locate the remote subdev connected to the sink pad. If the remote pad is null, the driver dereferences it, leading to a crash. The crash can be prevented by checking if the pad is null before using it and returning an error if it is.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
