CVE-2023-52894

A vulnerability was found in the Linux kernel's USB f_ncm.c driver where a lack of proper sanitization can result in a potential NULL pointer dereference in the ncm_bitrate() function. This issue can occur if cdev->gadget happens to be NULL when it is referenced by the ncm_bitrate() function, which then passes it to the gadget_is_superspeed() function, where the eventual NULL pointer dereference occurs. This vulnerability potentially leads to undefined behavior or crashes.
