CyberRota Analysis
AI-GeneratedThe vulnerability affects the txgbe driver in the Linux kernel, where FDIR filters can leak when the driver is removed while the network interface is down. This can lead to resource exhaustion and potential denial of service due to untracked filters remaining in memory. Organizations using the Linux kernel with the txgbe driver should prioritize this issue to prevent potential network performance degradation and ensure proper resource management.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: fix FDIR filter leak on remove Perfect FDIR filters can be added while the interface is down and are kept on the software list for later restore. unregister_netdev() only calls ndo_stop when the device is up, so txgbe_fdir_filter_exit() in txgbe_close() is skipped in that case and the filters are leaked on driver remove. Free the filter list from txgbe_remove() as well.
