CVE-2026-68321Source published Source updated
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. A resource leak vulnerability exists in the txgbe network driver. This flaw occurs because Flow Director (FDIR) filters are not properly freed when the network interface is removed while it is in a down state. This can lead to a gradual consumption of system resources, potentially resulting in a Denial of Service (DoS) over time. This issue…
