"The version of kernel installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-46746 advisory.

  - 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: [ 13.050438]
