  Vector：CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:wifi: ath11k: update channel list in reg notifier instead reg workerCurrently when ath11k gets a new channel list, it will be processedaccording to the following steps:1. update new channel list to cfg80211 and queue reg_work.2. cfg80211 handles new channel list during reg_work.3. update cfg80211 s handled channel list to firmware byath11k_reg_update_chan_list().But ath11k will immediately execute step 3 after reg_work is justqueued. Since step 2 is asynchronous, cfg80211 may not have completedhandling the new channel list, which may leading to an out-of-boundswrite error:BUG: KASAN: slab-out-of-bounds in ath11k_reg_update_chan_listCall Trace:    ath11k_reg_update_chan_list+0xbfe/0xfe0 [ath11k]    kfree+0x109/0x3a0    ath11k_regd_update+0x1cf/0x350 [ath11k]    ath11k_regd_update_work+0x14/0x20 [ath11k]    process_one_work+0xe35/0x14c0Should ensure step 2 is completely done before executing step 3. ThusWen raised patch[1]. When flag NL80211_REGDOM_SET_BY_DRIVER is set,cfg80211 will notify ath11k after step 2 is done.So enable the flag NL80211_REGDOM_SET_BY_DRIVER then cfg80211 willnotify ath11k after step 2 is done. At this time, there will be noKASAN bug during the execution of the step 3.[1] https://patchwork.kernel.org/project/linux-wireless/patch/
