Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device In case devcom allocation is failed, mlx5 is always freeing the priv. However, this priv might have been allocated by a different thread, and freeing it might lead to use-after-free bugs. Fix it by freeing the priv only in case it was allocated by the running thread.
