Description

In the Linux kernel, the following vulnerability has been resolved: net: txgbe: leave space for null terminators on property_entry Lists of struct property_entry are supposed to be terminated with an empty property, this driver currently seems to be allocating exactly the amount of entry used. Change the struct definition to leave an extra element for all property_entry.

Executive Summary

This vulnerability exists in the Linux kernel's txgbe network driver. The issue is that lists of struct property_entry are supposed to be terminated with an empty property, but the driver was allocating exactly the amount of entries used without leaving space for a null terminator. This could lead to improper handling of property lists.

The fix involved changing the struct definition to leave an extra element for all property_entry lists, ensuring proper termination with a null property.

Impact Analysis

This vulnerability relates to the Linux kernel's txgbe driver not allocating enough space for null terminators in property_entry lists, which are supposed to be terminated with an empty property. The issue could potentially lead to improper handling of property lists, possibly causing unexpected behavior or memory issues in the affected driver.
