CVE-2025-21714 is a use-after-free vulnerability in the Linux kernel RDMA mlx5 driver's implicit on-demand paging (ODP) memory-region destruction path. Repeated invalidation of an implicit ODP memory region could queue its destruction work more than once. The first work item can free the memory region, after which a second queued work item may execute against the freed object. The corrective change uses __xa_cmpxchg() to ensure destruction is initiated only once for a given memory region.
