In the Linux kernel, the following vulnerability has been resolved:net: phy: qcom: at803x: fix kernel panic with at8031_probeOn reworking and splitting the at803x driver, in splitting function ofat803x PHYs it was added a NULL dereference bug where priv is referencedbefore it s actually allocated and then is tried to write to for theis_1000basex and is_fiber variables in the case of at8031, writing onthe wrong address.Fix this by correctly setting priv local variable only afterat803x_probe is called and actually allocates priv in the phydev struct.
