Details

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 'priv->ports[]' is INNO_PHY_PORT_NUM.

In the for loop, 'i' is used as the index for array 'priv->ports[]' with a check (i > INNO_PHY_PORT_NUM) which indicates that INNO_PHY_PORT_NUM is allowed value for 'i' 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
