In the Linux kernel, the following vulnerability has been resolved:
net: txgbe: fix heap overflow when reading module EEPROM
txgbe_read_eeprom_hostif() always copies round_up(length, 4) bytes
into the caller buffer, which ethtool allocates with exactly 'length'
bytes. A non-4-aligned length therefore causes an out-of-bounds write.
Copy only the remaining bytes on the final dword instead.
