Details

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: LAG, MPESW, Fix missing complete() on devcom error

mlx5_mpesw_work() returned without calling complete() when mlx5_lag_get_devcom_comp() returned NULL. A caller that queued the work and waited on mpesww->comp would block indefinitely.
