HID: ntrig: validate feature report details

2013-09-26T23:52:48+00:00

commit 875b4e3763dbc941f15143dd1a18d10bb0be303b upstream. A HID device could send a malicious feature report that would cause the ntrig HID driver to trigger a NULL dereference during initialization: [57383.031190] usb 3-1: New USB device found, idVendor=1b96, idProduct=0001 ...

HID: validate HID report id size

2013-09-26T23:52:48+00:00

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: pantherlord: validate output report details

2013-09-26T23:52:47+00:00

commit 412f30105ec6735224535791eed5cdc02888ecb4 upstream. A HID device could send a malicious output report that would cause the pantherlord HID driver to write beyond the output report allocation during initialization, causing a heap overflow: [ 310.939483] usb 1-1: New USB device found, idVendor=0e8f, idProduct=0003 ...

commit a1c781bb20ac1e03280e420abd47a99eb8bbdd3b upstream. They are not implemented, and accessing them might trigger errors Signed-off-by: Felix Fietkau Signed-off-by: John W. Linville Signed-off-by: Greg Kroah-Hartman

ath9k: always clear ps filter bit on new assoc

2013-09-26T23:52:47+00:00

commit 026d5b07c03458f9c0ccd19c3850564a5409c325 upstream. Otherwise in some cases, EAPOL frames might be filtered during the initial handshake, causing delays and assoc failures. Signed-off-by: Felix Fietkau Signed-off-by: John W. Linville Signed-off-by: Greg Kroah-Hartman

usb: config->desc.bLength may not exceed amount of data returned by the device

2013-09-26T23:52:47+00:00

commit b4f17a488ae2e09bfcf95c0e0b4219c246f1116a upstream. While reading the config parsing code I noticed this check is missing, without this check config->desc.wTotalLength can end up with a value larger then the dev->rawdescriptors length for the config, and when userspace then tries to get the rawdescriptors bad things may happen.
