xhci: xhci-mem: off by one in xhci_stream_id_to_ring()

2018-07-17T09:31:43+00:00

commit 313db3d6488bb03b61b99de9dbca061f1fd838e1 upstream.

The > should be >= here so that we don't read one element beyond the end
of the ep->stream_info->stream_rings[] array.

usb: quirks: add delay quirks for Corsair Strafe

2018-07-17T09:31:43+00:00

commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream.

Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.

With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.

USB: serial: mos7840: fix status-register error handling

2018-07-17T09:31:43+00:00

commit 794744abfffef8b1f3c0c8a4896177d6d13d653d upstream.

Add missing transfer-length sanity check to the status-register
completion handler to avoid leaking bits of uninitialised slab data to
user space.

USB: yurex: fix out-of-bounds uaccess in read handler

2018-07-17T09:31:43+00:00

commit f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 upstream.

In general, accessing userspace memory beyond the length of the supplied
buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via
sys_splice()) and privilege escalation inside userspace.

Fix it by using simple_read_from_buffer() instead of custom logic.

commit 01b3cdfca263a17554f7b249d20a247b2a751521 upstream.

Fix broken modem-status error handling which could lead to bits of slab
data leaking to user space.

USB: serial: cp210x: add another USB ID for Qivicon ZigBee stick

commit 367b160fe4717c14a2a978b6f9ffb75a7762d3ed upstream.

There are two versions of the Qivicon Zigbee stick in circulation. This
adds the second USB ID to the cp210x driver.

USB: serial: ch341: fix type promotion bug in ch341_control_in()

2018-07-17T09:31:43+00:00

commit e33eab9ded328ccc14308afa51b5be7cbe78d30b upstream.

The "r" variable is an int and "bufsize" is an unsigned int so the
comparison is type promoted to unsigned.  If usb_control_msg() returns a
negative that is treated as a high positive value and the error handling
doesn't work.

USB: serial: cp210x: add Silicon Labs IDs for Windows Update

2018-07-11T14:03:46+00:00

commit 2f839823382748664b643daa73f41ee0cc01ced6 upstream.

Silicon Labs defines alternative VID/PID pairs for some chips that when
used will automatically install drivers for Windows users without manual
intervention. Unfortunately, these IDs are not recognized by the Linux
module, so using these IDs improves user experience on one platform but
degrades it on Linux. This patch addresses this problem.

usb: cdc_acm: Add quirk for Uniden UBC125 scanner

2018-07-11T14:03:46+00:00

commit 4a762569a2722b8a48066c7bacf0e1dc67d17fa1 upstream.

Uniden UBC125 radio scanner has USB interface which fails to work
with cdc_acm driver:
  usb 1-1.5: new full-speed USB device number 4 using xhci_hcd
  cdc_acm 1-1.5:1.0: Zero length descriptor references
  cdc_acm: probe of 1-1.5:1.0 failed with error -22

Adding the NO_UNION_NORMAL quirk for the device fixes the issue:
  usb 1-4: new full-speed USB device number 15 using xhci_hcd
  usb 1-4: New USB device found, idVendor=1965, idProduct=0018
