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. (NVD)
