    Описание

    Оригинално описание

    In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Sanitize the reply credit grant after parsing The out_norqst exit in rpcrdma_reply_handler() branches away before the credit clamp, so a reply that matches no pending request reaches out_post carrying the raw credit value parsed from the wire. rpcrdma_post_recvs() does not bound its @needed argument: the refill loop allocates and chains Receive WRs until the count is satisfied or allocation fails. A peer that sends a well-formed reply carrying an unknown XID and an inflated credit grant therefore drives rep allocation and Receive posting past re_max_requests on every such reply. Move the clamp to immediately after the credit field is parsed, ahead of the first branch that can reach out_post, so every later consumer sees a sanitized value. The cwnd update stays on the matched-request path.
