In the Linux kernel, the following vulnerability has been resolved: net/mlx5: LAG, Fix off-by-one in single-FDB error rollback On failure at index i, the reverse cleanup loop in mlx5_lag_create_single_fdb() starts from i, so the failed index itself is rolled back. That can operate on uninitialized state or double-tear-down a rule the add_one path already self-rolled-back. Start the rollback from i - 1 so only successfully-installed entries are undone.
