NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Centos.

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.
