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.
