Summary
net: txgbe: fix heap overflow when reading module EEPROM
Details

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

net: txgbe: fix heap overflow when reading module EEPROM

txgbereadeepromhostif() always copies roundup(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.
