LinuxVULNRICHMENT:CVE-2024-38619CVE-2024-38619 usb-storage: alauda: Check whether the media is initialized
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().
