How to fix?

Upgrade SLES:16.0.0 kernel-source to version 6.12.0-160000.36.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
