CVE-2026-68440Source published Source updated
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. A flaw was found in the Linux kernel's txgbe network driver. When reading module EEPROM (Electrically Erasable Programmable Read-Only Memory), the txgbe_read_eeprom_hostif() function can attempt to copy more data than the allocated buffer size if the data length is not a multiple of four. This out-of-bounds write can lead to memory corruption, potentially causing system instability or a denial of…
