Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ipvs: do not keep dest_dst if dev is going down<br />
<br />
There is race between the netdev notifier ip_vs_dst_event()<br />
and the code that caches dst with dev that is going down.<br />
As the FIB can be notified for the closed device after our<br />
handler finishes, it is possible valid route to be returned<br />
and cached resuling in a leaked dev reference until the dest<br />
is not removed.<br />
<br />
To prevent new dest_dst to be attached to dest just after the<br />
handler dropped the old one, add a netif_running() check<br />
to make sure the notifier handler is not currently running<br />
for device that is closing.
