  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nusb: gadget: renesas_usb3: validate endpoint index in standard request handlers\nThe GET_STATUS and SET/CLEAR_FEATURE handlers extract the endpoint\nnumber from the host-supplied wIndex without any sort of validation.\nFix this up by validating the number of endpoints actually match up with\nthe number the device has before attempting to dereference a pointer\nbased on this math.\nThis is just like what was done in commit ee0d382feb44 (\"usb: gadget:\naspeed_udc: validate endpoint index for ast udc\") for the aspeed driver.", "A flaw was found in the Linux kernel's renesas_usb3 and aspeed_udc drivers. These drivers did not properly validate endpoint index numbers provided by a host during standard USB requests, such as GET_STATUS and SET/CLEAR_FEATURE. This oversight could allow an attacker to provide a crafted endpoint number, potentially leading to an out-of-bounds pointer dereference. Such an issue may result in a denial of service or other unpredictable system behavior." ],
