In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: 8192cu: fix tid out of range in rtl92cu_tx_fill_desc() TID getting from ieee80211_get_tid() might be out of range of array size of sta_entry->tids[], so check TID is less than MAX_TID_COUNT. Othwerwise, UBSAN warn: UBSAN: array-index-out-of-bounds in drivers/net/wireless/realtek/rtlwifi/rtl8192cu/trx.c:514:30 index 10 is out of range for type 'rtl_tid_data [9]'
