CVE-2024-46746: HID: amd_sfh: free driver_data after destroying hid device
In the Linux kernel, the following vulnerability has been resolved:

HID: amd_sfh: free driver_data after destroying hid device

HID driver callbacks aren't called anymore once hid_destroy_device() has
been called. Hence, hid driver_data should be freed only after the
hid_destroy_device() function returned as driver_data is used in several
callbacks.

I observed a crash with kernel 6.10.0 on my T14s Gen 3, after enabling
KASAN to debug memory allocation, I got this output:
