This causes netif_device_detach/attach to\noperate on an ieee80211_hw struct, reading and writing at wrong\noffsets.  The adjacent io_slot_reset() already does it correctly.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.\n\nTested on RTL8852CE by calling the handlers from a test module\nbefore and after the fix.\n\n## Affected\n\n- `Linux >= 16e3d93c6183649a3b210f82b83c1cb12aa5e8a3 < aefc30e4a829c1683f6ae999df7f9310c27eae6c`\n- `Linux >= 16e3d93c6183649a3b210f82b83c1cb12aa5e8a3 < c1907b9a4fa9cb33d11a9af138374dd2e93f7a93`\n- `Linux >= 16e3d93c6183649a3b210f82b83c1cb12aa5e8a3 < 7068c379cf9aa8afe4dce4d9d82390187aa9c4d0`\n- `Linux 6.17`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
