In the Linux kernel, the following vulnerability has been resolved:
usb-storage: alauda: Check whether the media is initialized
The member "uzonesize" of struct alaudainfo will remain 0 if alaudainitmedia() fails, potentially causing divide errors in alaudareaddata() and alaudawritelba(). - Add a member "mediainitialized" to struct alaudainfo. - Change a condition in alaudacheckmedia() to ensure the first initialization. - Add an error check for the return value of alaudainit_media().
