          "details": "To mitigate this issue, prevent the `ath12k` module from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically. Note that this will make hardware that uses that chipset unavailable, so this mitigation is not suitable for systems that rely on Qualcomm Wi-Fi 7 network adapters.",
