CVE-2026-74459

can: etas_es58x: es58x_read_bulk_callback(): fix RX buffer leak on URB resubmit failure

In the Linux kernel, the following vulnerability has been resolved:

can: etas_es58x: es58x_read_bulk_callback(): fix RX buffer leak on URB resubmit failure

es58x_read_bulk_callback() resubmits the RX URB after processing a received
packet. If the resubmit succeeds, the URB remains anchored and will be
handled by the normal RX path or by teardown.

However, if usb_submit_urb() fails, the callback unanchors the URB and then
returns directly. This skips the existing free_urb path, so the coherent
transfer buffer allocated with usb_alloc_coherent() is not released.

Reuse the existing free_urb path after a resubmit failure so that the RX
coherent buffer is freed before leaving the callback.
