CVE-2026-97541: wifi: ath9k_htc: don't store usb_device_id

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

Description
===========

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k_htc: don't store usb_device_id

usb_device_id is not guaranteed to live longer than probe due to presence
of dynamic ID. All information apart from driver_data can be easily
retrieved from usb_device, so just store driver_data.

The Linux kernel CVE team has assigned CVE-2026-97541 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
