However, because of\nthe order in which things are initialised, this is not guaranteed to be the\ncase, because the device is exposed to the USB subsystem before the ath9k driver\ninitialisation is completed.\n\nWe already committed a partial fix for this in commit:\n8b3046abc99e (\"ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()\")\n\nHowever, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event\ntasklet, pairing it with an \"initialisation complete\" bit in the TX struct. It\nseems syzbot managed to trigger the race for one of the other commands as well,\nso let's just move the existing synchronisation bit to cover the whole\ntasklet (setting it at the end of ath9k_htc_probe_device() instead of inside\nath9k_tx_init())." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
