- Summary
- usb: gadget: r8a66597: avoid double free of ep0_req in probe error path
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: r8a66597: avoid double free of ep0_req in probe error path
If usb_add_gadget_udc() fails, r8a66597_probe() jumps to err_add_udc and frees ep0_req, then falls through to clean_up2 where ep0_req is freed again when it is non-NULL.
Remove the redundant free from err_add_udc and keep the cleanup in clean_up2 so the request is released exactly once.
Issue found using a prototype static analysis tool and confirmed by code review.
