AI-suggested
A fix has been implemented in the Linux kernel to address this issue by changing the data stored from usb_device_id to driver_data. Users should apply the updated kernel versions containing this fix to remediate the vulnerability.
Description
A vulnerability in the Linux kernel's ath9k_htc WiFi driver was resolved. The issue involved storing the usb_device_id, which is not guaranteed to persist beyond the probe phase due to dynamic IDs. The fix involves storing only driver_data, which is reliably retrievable from the usb_device structure.
