HID: LG: validate HID output report details

2013-10-05T14:06:54Z

commit 0fb6bd06e06792469acc15bbe427361b56ada528 upstream. A HID device could send a malicious output report that would cause the lg, lg3, and lg4 HID drivers to write beyond the output report allocation during an event, causing a heap overflow: [ 325.245240] usb 1-1: New USB device found, idVendor=046d, idProduct=c287 ... [ 414.518960] BUG kmalloc-4096 (Not tainted): Redzone overwritten Additionally, while lg2 did correctly validate the report details, it was cleaned up and shortened.

HID: logitech-dj: validate output report details

commit 297502abb32e225fb23801fcdb0e4f6f8e17099a upstream. A HID device could send a malicious output report that would cause the logitech-dj HID driver to leak kernel memory contents to the device, or trigger a NULL dereference during initialization: [ 304.424553] usb 1-1: New USB device found, idVendor=046d, idProduct=c52b ...

HID: zeroplus: validate output report details

2013-10-01T16:10:51Z

commit 78214e81a1bf43740ce89bb5efda78eac2f8ef83 upstream. The zeroplus HID driver was not checking the size of allocated values in fields it used. A HID device could send a malicious output report that would cause the driver to write beyond the output report allocation during initialization, causing a heap overflow: [ 1442.728680] usb 1-1: New USB device found, idVendor=0c12, idProduct=0005 ...

HID: provide a helper for validating hid reports

2013-10-01T16:10:51Z

commit 331415ff16a12147d57d5c953f3a961b7ede348b upstream. Many drivers need to validate the characteristics of their HID report during initialization to avoid misusing the reports. This adds a common helper to perform validation of the report exisitng, the field existing, and the expected number of values within the field.

HID: validate HID report id size

2013-09-27T00:15:34Z

commit 43622021d2e2b82ea03d883926605bdd0525e1d1 upstream. The "Report ID" field of a HID report is used to build indexes of reports. The kernel's index of these is limited to 256 entries, so any malicious device that sets a Report ID greater than 255 will trigger memory corruption on the host: [ 1347.156239] BUG: unable to handle kernel paging request at ffff88094958a878 [ 1347.156261] IP: [] hid_register_report+0x2a/0x8b CVE-2013-2888 Signed-off-by: Kees Cook Signed-off-by: Jiri Kosina Signed-off-by: Greg Kroah-Hartman

HID: Fix Speedlink VAD Cezanne support for some devices

2013-09-27T00:15:34Z

commit 06bb5219118fb098f4b0c7dcb484b28a52bf1c14 upstream. Some devices of the "Speedlink VAD Cezanne" model need more aggressive fixing than already done. I made sure through testing that this patch would not interfere with the proper working of a device that is bug-free. (The driver drops EV_REL events with abs(val) >= 256, which are not achievable even on the highest laser resolution hardware setting.)
