Vulnerability from github
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:
