Descriptions

An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93.

Se detectó un problema en el subsistema stv06xx en el kernel de Linux versiones anteriores a 5.6.1. Los archivos drivers/media/usb/gspca/stv06xx/stv06xx.c y drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c manejan inapropiadamente los descriptores no válidos, como es demostrado por una desreferencia del puntero NULL, también se conoce como CID-485b06aadb93.
