Description OSIDB Bzimport 2025-03-27 17:04:04 UTC 
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().
