Description OSIDB Bzimport 2026-05-06 13:03:39 UTC 
In the Linux kernel, the following vulnerability has been resolved:

HID: logitech-hidpp: Check maxfield in hidpp_get_report_length()

Do not crash when a report has no fields.

Fake USB gadgets can send their own HID report descriptors and can define report
structures without valid fields.  This can be used to crash the kernel over USB.
