CVE-2026-93109
In the Linux kernel, the following vulnerability has been resolved:

RDMA/mlx5: Drain RCU callbacks during module teardown

devx_free_subscription() can remain queued after the last DevX event file
drops its module reference or an auxiliary driver detaches its devices.
mlx5_ib can then unload before the callback runs.

Registration error unwind has the same risk because driver registration
can attach existing devices before failing. Wait after all drivers have
stopped.
