Pending analysis

CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: add NULL check in eswitch lag check<br /> <br /> The function ice_lag_is_switchdev_running() is being called from outside of<br /> the LAG event handler code. This results in the lag-&gt;upper_netdev being<br /> NULL sometimes. To avoid a NULL-pointer dereference, there needs to be a<br /> check before it is dereferenced.
