Description OSIDB Bzimport 2026-08-28 07:42:05 UTC 
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.

Funnel the early-return path through a new "complete" label so the
waiter is always woken.
