This commit adds the missing size validation for Rock Band 3 PS3 Pro
instruments in sony_raw_event(), this prevents a malicious device from

Rosalie Wanders a4170b63ed HID: sony: add missing size validation for SMK-Link remotes
This commit adds the missing size validation for SMK-Link remotes in
sony_raw_event(), this prevents a malicious device from allowing
hid-sony to read out of bounds of the provided buffer.

I do not own these devices so the size check only forces that the buffer
is large enough for nsg_mrxu_parse_report().

Michael Zaidman 80c4bbb2b3 HID: ft260: validate i2c input report length
Add two checks to ft260_raw_event() to prevent out-of-bounds reads
from malicious or malfunctioning devices:

First, reject reports shorter than the 2-byte header (report ID +
length fields). Without this, even accessing xfer->length on a
1-byte report is an OOB read.

Second, validate xfer->length against the actual data capacity of
the received HID report. Each I2C data report ID (0xD0 through
0xDE) defines a different report size in the HID descriptor, so the
available payload varies per report. A corrupted length field could
cause memcpy to read beyond the report buffer.

Greg Kroah-Hartman 69c02ffde6 HID: core: clamp report_size in s32ton() to avoid undefined shift
s32ton() shifts by n-1 where n is the field's report_size, a value that
comes directly from a HID device.  The HID parser bounds report_size
only to <= 256, so a broken HID device can supply a report descriptor
with a wide field that triggers shift exponents up to 256 on a 32-bit
type when an output report is built via hid_output_field() or
hid_set_field().

Commit ec61b41918 ("HID: core: fix shift-out-of-bounds in
hid_report_raw_event") added the same n > 32 clamp to the function
snto32(), but s32ton() was never given the same fix as I guess syzbot
hadn't figured out how to fuzz a device the same way.

Fix this up by just clamping the max value of n, just like snto32()
does.

Benjamin Tissoires 8b9a097eb2 HID: logitech-dj: fix wrong detection of bad DJ_SHORT output report
commit b6a5791285 ("HID: logitech-dj: Prevent REPORT_ID_DJ_SHORT
related user initiated OOB write") assumed that all HID devices attached
to the logitech-dj driver was having an output report of DJ_SHORT.

However, on the receiver itself, we have 2 other HID device we attach
here: the mouse emulation and the keyboard emulation. For those devices
the value of rep is NULL and we are triggered a segfault here.

This is doubly required because logitech-dj also handles non DJ devices
that might not have the DJ collection.

Benoît Sevens e2aaf2d3ad HID: logitech-hidpp: fix race condition when accessing stale stack pointer
The driver uses hidpp->send_receive_buf to point to a stack-allocated
buffer in the synchronous command path (__do_hidpp_send_message_sync).
However, this pointer is not cleared when the function returns.

If an event is processed (e.g. by a different thread) while the
send_mutex is held by a new command, but before that command has
updated send_receive_buf, the handler (hidpp_raw_hidpp_event) will
observe that the mutex is locked and dereference the stale pointer.

This results in an out-of-bounds access on a different thread's kernel
stack (or a NULL pointer dereference on the very first command).

Fix this by:
1. Clearing hidpp->send_receive_buf to NULL before releasing the mutex
   in the synchronous command path.
2. Moving the assignment of the local 'question' and 'answer' pointers
   inside the mutex_is_locked() block in the handler, and adding
   a NULL check before dereferencing.

Dmitry Torokhov 590204185d HID: core: do not allow parsing 0-sized reports
Commit d7db259bd6 ("HID: core: factor out hid_parse_collections()")
reworked collection parsing code and inadvertently allowed returning
"success" when parsing 0-sized reports where old code returned -EINVAL.

Restore the original behavior by doing an explicit check.

Note that the error message now differs from the generic "item fetching
failed at offset %u/%u" that is now used only for non-empty descriptors.
