CVE-2023-53015 Information

Description

In the Linux kernel the following vulnerability has been resolved:

HID: betop: check shape of output reports

betopff_init() only checks the total sum of the report counts for each report field to be at least 4 but hid_betopff_play() expects 4 report fields. A device advertising an output report with one field and 4 report counts would pass the check but crash the kernel with a NULL pointer dereference in hid_betopff_play().
