AI-Generated

A heap overflow vulnerability exists in the Linux kernel's txgbe driver, specifically in the txgbe_read_eeprom_hostif() function, which improperly copies data into a buffer, potentially leading to out-of-bounds writes. This flaw could allow an attacker to exploit memory corruption, potentially leading to system crashes or arbitrary code execution. Organizations using affected Linux systems, particularly those relying on the txgbe driver for network interfaces, should prioritize applying patches to mitigate this risk.

Original NVD Description

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.
