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 '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 ite…
