This causes netif_device_detach/attach to\noperate on an ieee80211_hw struct, reading and writing at wrong\noffsets.\n\nUse ieee80211_stop_queues/wake_queues instead, consistent with\nevery other queue stop/start path in the driver.\n\n## Affected\n\n- `Linux >= cdb82c80b9349ed1d9ce6b49856128e04f4effc9 < 1ef3d1338d94ec41f58fbfb6ba7742a27ea61d89`\n- `Linux >= cdb82c80b9349ed1d9ce6b49856128e04f4effc9 < d7920797f721f944861f3c48ffb2b73f84b631fe`\n- `Linux >= cdb82c80b9349ed1d9ce6b49856128e04f4effc9 < 706183dbef4a79d120d4e928f693bea50df496f8`\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":[]}
