Description

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

net: lan743x: Modify the EEPROM and OTP size for PCI1xxxx devices

Maximum OTP and EEPROM size for hearthstone PCI1xxxx devices are 8 Kb
and 64 Kb respectively. Adjust max size definitions and return correct
EEPROM length based on device. Also prevent out-of-bound read/write.
