+Subject: [PATCH] HID: magicmouse: sanity check report size in raw_event()
+ callback
+
+The report passed to us from transport driver could potentially be
+arbitrarily large, therefore we better sanity-check it so that
+magicmouse_emit_touch() gets only valid values of raw_id.
+
+This fixes CVE-2014-3181

+Subject: [PATCH] HID: logitech: perform bounds checking on device_id early
+ enough
+
+device_index is a char type and the size of paired_dj_deivces is 7
+elements, therefore proper bounds checking has to be applied to
+device_index before it is used.
+
+We are currently performing the bounds checking in
+logi_dj_recv_add_djhid_device(), which is too late, as malicious device
+could send REPORT_TYPE_NOTIF_DEVICE_UNPAIRED early enough and trigger the
+problem in one of the report forwarding functions called from
+logi_dj_raw_event().
+
+Fix this by performing the check at the earliest possible ocasion in
+logi_dj_raw_event().
+
+This fixes CVE-2014-3182

+Subject: [PATCH] USB: whiteheat: Added bounds checking for bulk command
+ response
+
+This patch fixes a potential security issue in the whiteheat USB driver
+which might allow a local attacker to cause kernel memory corrpution. This
+is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On
+EHCI and XHCI busses it's possible to craft responses greater than 64
+bytes leading a buffer overflow.
+
+This fixes CVE-2014-3185
