  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nwifi: ath9k: verify the expected usb_endpoints are present\nThe bug arises when a USB device claims to be an ATH9K but doesn't\nhave the expected endpoints. (In this case there was an interrupt\nendpoint where the driver expected a bulk endpoint.) The kernel\nneeds to be able to handle such devices without getting an internal error.\nusb 1-1: BOGUS urb xfer, pipe 3 != type 1\nWARNING: CPU: 3 PID: 500 at drivers/usb/core/urb.c:493 usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493\nModules linked in:\nCPU: 3 PID: 500 Comm: kworker/3:2 Not tainted 5.10.135-syzkaller #0\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014\nWorkqueue: events request_firmware_work_func\nRIP: 0010:usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493\nCall Trace:\nath9k_hif_usb_alloc_rx_urbs drivers/net/wireless/ath/ath9k/hif_usb.c:908 [inline]\nath9k_hif_usb_alloc_urbs+0x75e/0x1010 drivers/net/wireless/ath/ath9k/hif_usb.c:1019\nath9k_hif_usb_dev_init drivers/net/wireless/ath/ath9k/hif_usb.c:1109 [inline]\nath9k_hif_usb_firmware_cb+0x142/0x530 drivers/net/wireless/ath/ath9k/hif_usb.c:1242\nrequest_firmware_work_func+0x12e/0x240 drivers/base/firmware_loader/main.c:1097\nprocess_one_work+0x9af/0x1600 kernel/workqueue.c:2279\nworker_thread+0x61d/0x12f0 kernel/workqueue.c:2425\nkthread+0x3b4/0x4a0 kernel/kthread.c:313\nret_from_fork+0x22/0x30 arch/x86/entry/entry_64.S:299\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller." ],
