5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

In the Linux kernel, the following vulnerability has been resolved:

net: phy: dp83822: Fix NULL pointer dereference on DP83825 devices

The probe() function is only used for DP83822 and DP83826 PHY, leaving the private data pointer uninitialized for the DP83825 models which causes a NULL pointer dereference in the recently introduced/changed functions dp8382x_config_init() and dp83822_set_wol().

Add the dp8382x_probe() function, so all PHY models will have a valid private data pointer to fix this issue and also prevent similar issues in the future.
