Description OSIDB Bzimport 2025-02-26 03:13:21 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: phy: micrel: Allow probing without .driver_data

Currently, if the .probe element is present in the phy_driver structure
and the .driver_data is not, a NULL pointer dereference happens.

Allow passing .probe without .driver_data by inserting NULL checks
for priv->type.
