CVE-2026-31615

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: gadget: renesas_usb3: validate endpoint index in standard request handlers<br /> <br /> The GET_STATUS and SET/CLEAR_FEATURE handlers extract the endpoint<br /> number from the host-supplied wIndex without any sort of validation.<br /> Fix this up by validating the number of endpoints actually match up with<br /> the number the device has before attempting to dereference a pointer<br /> based on this math.<br /> <br /> This is just like what was done in commit ee0d382feb44 ("usb: gadget:<br /> aspeed_udc: validate endpoint index for ast udc") for the aspeed driver.
