Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-17 18:32

Details

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.
