Description

In the Linux kernel, the following vulnerability has been resolved: phy: hisilicon: Fix an out of bounds check in hisi_inno_phy_probe() The size of array &#39;priv->ports[]&#39; is INNO_PHY_PORT_NUM. In the for loop, &#39;i&#39; is used as the index for array &#39;priv->ports[]&#39; with a check (i > INNO_PHY_PORT_NUM) which indicates that INNO_PHY_PORT_NUM is allowed value for &#39;i&#39; in the same loop. This > comparison needs to be changed to >=, otherwise it potentially leads to an out of bounds write on the next iteration through the loop
