CVE-2026-46053
Description
AI Translation Available
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.
