CVE-2024-38619

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

usb-storage: alauda: Check whether the media is initialized

The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba().

• Add a member "media_initialized" to struct alauda_info.
• Change a condition in alauda_check_media() to ensure the first initialization.
• Add an error check for the return value of alauda_init_media().
