fkie_cve-2026-31633

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

rxrpc: Fix integer overflow in rxgk_verify_response()

In rxgk_verify_response(), there's a potential integer overflow due to rounding up token_len before checking it, thereby allowing the length check to be bypassed.

Fix this by checking the unrounded value against len too (len is limited as the response must fit in a single UDP packet).
