Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in the Linux kernel's net driver phy_device.c in the phy_get_internal_delay() function, where a lack of proper checks can cause a potential NULL pointer dereference to occur when the function attempts to access an empty array. The error occurs if the driver calls phy_get_internal_delay() without defining delay_values and rx-internal-delay-ps or tx-internal-delay-ps is set to 0 in the device-tree. This flaw can lead to system instability.
