Summary
In the Linux kernel, the following vulnerability has been resolved: media: mceusb: Use new usb_control_msg_*() routines Automatic kernel fuzzing led to a WARN about invalid pipe direction in the mceusb driver: ------------[ cut here ]------------ usb 6-1: BOGUS control dir, pipe 80000380 doesn't match bRequestType 40 WARNING: CPU: 0 PID: 2465 at drivers/usb/core/urb.c:410 usb_submit_urb+0x1326/0x1820 drivers/usb/core/urb.c:410 Modules linked in: CPU: 0 PID: 2465 Comm: kworker/0:2 Not tainted 5.19.0-rc4-00208-g69cb6c6556ad #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 Workqueue: usb_hub_wq hub_event RIP: 0010:usb_submit_urb+0x1326/0x1820 drivers/usb/core/urb.c:410 Code: 7c 24 40 e8 ac 23 91 fd 48 8b 7c 24 40 e8 b2 70 1b ff 45 89 e8 44 89 f1 4c 89 e2 48 89 c6 48 c7 c7 a0 30 a9 86 e8 48 07 11 02 <0f> 0b e9 1c f0 ff ff e8 7e 23 91 fd 0f b6 1d 63 22 83 05 31 ff 41 RSP: 0018:ffffc900032becf0 EFLAGS: 00010282 RAX: 0000000000000000 RBX: ffff8881100f3058 RCX: 0000000000000000 RDX: ffffc90004961000 RSI: ffff888114c6d580 RDI: fffff52000657d90 RBP: ffff888105ad90f0 R08: ffffffff812c3638 R09: 0000000000000000 R10: 0000000000000005 R11: ffffed1023504ef1 R12: ffff888105ad9000 R13: 0000000000000040 R14: 0000000080000380 R15: ffff88810ba96500 FS: 0000000000000000(0000) GS:ffff88811a800000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ffe810bda58 CR3: 000000010b720000 CR4: 0000000000350ef0 Call Trace: <TASK> usb_start_wait_urb+0x101/0x4c0 drivers/usb/core/message.c:58 usb_internal_control_msg drivers/usb/core/message.c:102 [inline] usb_control_msg+0x31c/0x4a0 drivers/usb/core/message.c:153 mceusb_gen1_init drivers/media/rc/mceusb.c:1431 [inline] mceusb_dev_probe+0x258e/0x33f0 drivers/media/rc/mceusb.c:1807 The reason for the warning is clear enough; the driver sends an unusual read request on endpoint 0 but does not set the USB_DIR_IN bit in the bRequestType field. More importantly, the whole situation can be avoided and the driver simplified by converting it over to the relatively new usb_control_msg_recv() and usb_control_msg_send() routines. That's what this fix does.
