CyberRota Analysis
AI-GeneratedA vulnerability in the Linux kernel's ethtool component could lead to a crash when an error occurs during the preparation of a generic netlink message. If the ethnl_tsinfo_prepare_dump() function fails, the subsequent call to genlmsg_cancel() with an error pointer may result in a system instability. Linux system administrators and developers should prioritize this issue to prevent potential disruptions in network management functionalities.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure The goto err label leads to: genlmsg_cancel(skb, ehdr); return ret; If ethnl_tsinfo_prepare_dump() failed, it has not started a genlmsg. There's nothing to cancel, and passing an error pointer to genlmsg_cancel() would cause a crash.
