Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A crash can occur in the
ethtool component when ethnl tsinfo prepare dump() fails. The issue arises because the system attempts to call the genlmsg cancel() function using an error pointer (ERR PTR) before a generic netlink message has actually been started. This improper handling of the error state leads to a system crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
