Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net: rds: fix MR cleanup on copy error __rds_rdma_map() hands sg/pages ownership to the transport after get_mr() succeeds. If copying the generated cookie back to user space fails after that point, the error path must not free those resources again before dropping the MR reference. Remove the duplicate unpin/free from the put_user() failure branch so that MR teardown is handled only through the existing final cleanup path.
