-Subject: ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb
-
-commit 2bbcaaee1fcbd83272e29f31e2bb7e70d8c49e05 upstream.
-
-In ath9k_hif_usb_rx_cb interface number is assumed to be 0.
-usb_ifnum_to_if(urb->dev, 0)
-But it isn't always true.
-
-The case reported by syzbot:
-https://lore.kernel.org/linux-usb/000000000000666c9c05a1c05d12@google.com
-usb 2-1: new high-speed USB device number 2 using dummy_hcd
-usb 2-1: config 1 has an invalid interface number: 2 but max is 0
-usb 2-1: config 1 has no interface number 0
-usb 2-1: New USB device found, idVendor=0cf3, idProduct=9271, bcdDevice=
-1.08
-usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
-general protection fault, probably for non-canonical address
-0xdffffc0000000015: 0000 [#1] SMP KASAN
-KASAN: null-ptr-deref in range [0x00000000000000a8-0x00000000000000af]
