Descriptions

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

media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access

When translating source to sink streams in the crossbar subdev, the
driver tries to locate the remote subdev connected to the sink pad. The
remote pad may be NULL, if userspace tries to enable a stream that ends
at an unconnected crossbar sink. When that occurs, the driver
dereferences the NULL pad, leading to a crash.

Prevent the crash by checking if the pad is NULL before using it, and
return an error if it is.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: nxp: imx8-isi: compruebe si el crossbar pad no es NULL antes del acceso. Al traducir el código fuente a las secuencias receptoras en el subdev de la barra transversal, el controlador intenta localizar el subdev remoto conectado a la plataforma del fregadero. El pad remoto puede ser NULL, si el espacio de usuario intenta habilitar una secuencia que termina en un receptor de barra transversal no conectado. Cuando eso ocurre, el controlador elimina la referencia al pad NULL, lo que provoca un bloqueo. Evite el bloqueo verificando si el pad es NULL antes de usarlo y devuelva un error si lo es.
