Overview
CVE-2026-93109 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
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.
