Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ax25: Fix reference count leak issue of net_device<br /> <br /> There is a reference count leak issue of the object "net_device" in<br /> ax25_dev_device_down(). When the ax25 device is shutting down, the<br /> ax25_dev_device_down() drops the reference count of net_device one<br /> or zero times depending on if we goto unlock_put or not, which will<br /> cause memory leak.<br /> <br /> In order to solve the above issue, decrease the reference count of<br /> net_device after dev-&gt;ax25_ptr is set to null.
