Subject: KASAN: use-after-free Read in ath9k_hif_usb_rx_cb (2) should share
 the same root cause with "KASAN: slab-out-of-bounds Read in
 ath9k_hif_usb_rx_cb (2)"

Dear kernel developers,

I found that KASAN: use-after-free Read in ath9k_hif_usb_rx_cb (2) and
"KASAN: slab-out-of-bounds Read in ath9k_hif_usb_rx_cb (2)" should
share the same root cause.

The reasons for my above statement,  1) the stack trace is the same;
2) we observed two crash behaviors appear alternatively when you run
one PoC in its building environment multiple times. 3) their PoCs have
a really high similarity

If you can have any issues with this statement or our information is
useful for you, please let us know. Thanks very much.

My best regards to you.
