CVE-2025-23133

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: update channel list in reg notifier instead reg worker

Currently when ath11k gets a new channel list, it will be processed
according 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 by
ath11k_reg_update_chan_list().

But ath11k will immediately execute step 3 after reg_work is just
queued. Since step 2 is asynchronous, cfg80211 may not have completed
handling the new channel list, which may leading to an out-of-bounds
write error:
BUG: KASAN: slab-out-of-bounds in ath11k_reg_update_chan_list
Call 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+0xe35/0x14c0

Should ensure step 2 is completely done before executing step 3. Thus
Wen 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 will
notify ath11k after step 2 is done. At this time, there will be no
KASAN bug during the execution of the step 3.
