CVE-2026-46053

CVE-2026-46053 affects the Linux kernel RDS memory-registration cleanup. In net/rds, __rds_rdma_map() transfers ownership of sg/pages after get_mr(); if copying the cookie back to user space fails, resources could be freed more than once. The fix removes a duplicate unpin/free in the put_user() f...
