Answer in brief
CVE-2026-68321 records a Unknown severity vulnerability in net: txgbe: fix FDIR filter leak on remove. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
