Input: pegasus_notetaker - fix endpoint sanity check

2020-01-29T15:45:29+00:00

commit bcfcb7f9b480dd0be8f0df2df17340ca92a03b98 upstream. The driver was checking the number of endpoints of the first alternate setting instead of the current one, something which could be used by a malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer dereference.

Input: aiptek - fix endpoint sanity check

2020-01-29T15:45:29+00:00

commit 3111491fca4f01764e0c158c5e0f7ced808eef51 upstream. The driver was checking the number of endpoints of the first alternate setting instead of the current one, something which could lead to the driver binding to an invalid interface. This in turn could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

Input: gtco - bounds check collection indent level

2019-07-13T08:43:10+00:00

The GTCO tablet input driver configures itself from an HID report sent via USB during the initial enumeration process. Some debugging messages are generated during the parsing. A debugging message indentation counter is not bounds checked, leading to the ability for a specially crafted HID report to cause '-' and null bytes be written past the end of the indentation array. As long as the kernel has CONFIG_DYNAMIC_DEBUG enabled, this code will not be optimized out. This was discovered during code review after a previous syzkaller bug was found in this driver.
