Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue concerns a problem in the Linux kernel where the list usage in the dell rbu module is incorrect. This leads to incorrect data being shown when reading packet data via sysfs, and a NULL pointer dereference occurs when clearing the packet list. The problem is resolved by passing the correct list head to list for each entry*() when looping through the packet list.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
