CVE-2022-50297 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: verify the expected usb_endpoints are present The bug arises when a USB device claims to be an ATH9K but doesn't have the expected endpoints. (In this case there was an interrupt endpoint where the driver expected a bulk endpoint.) The kernel needs to be able to handle such devices without getting an internal error. usb 1-1: BOGUS urb xfer, pipe 3 != type 1 WARNING: CPU: 3 PID: 500 at drivers/usb/core/urb.c:493 usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493 Modules linked in: CPU: 3 PID: 500 Comm: kworker/3:2 Not tainted 5.10.135-syzkaller #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 Workqueue: events request_firmware_work_func RIP: 0010:usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493 Call Trace: ath9k_hif_usb_alloc_rx_urbs drivers/net/wireless/ath/ath9k/hif_usb.c:908 [inline] ath9k_hif_usb_alloc_urbs+0x75e/0x1010 drivers/net/wireless/ath/ath9k/hif_usb.c:1019 ath9k_hif_usb_dev_init drivers/net/wireless/ath/ath9k/hif_usb.c:1109 [inline] ath9k_hif_usb_firmware_cb+0x142/0x530 drivers/net/wireless/ath/ath9k/hif_usb.c:1242 request_firmware_work_func+0x12e/0x240 drivers/base/firmware_loader/main.c:1097 process_one_work+0x9af/0x1600 kernel/workqueue.c:2279 worker_thread+0x61d/0x12f0 kernel/workqueue.c:2425 kthread+0x3b4/0x4a0 kernel/kthread.c:313 ret_from_fork+0x22/0x30 arch/x86/entry/entry_64.S:299 Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
