Type:
CWE-476
NULL Pointer Dereference

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ice: always check VF VSI pointer values<br />
<br />
The ice_get_vf_vsi function can return NULL in some cases, such as if<br />
handling messages during a reset where the VSI is being removed and<br />
recreated.<br />
<br />
Several places throughout the driver do not bother to check whether this<br />
VSI pointer is valid. Static analysis tools maybe report issues because<br />
they detect paths where a potentially NULL pointer could be dereferenced.<br />
<br />
Fix this by checking the return value of ice_get_vf_vsi everywhere.
