Answer in brief
CVE-2026-74548 records a Unknown severity vulnerability in forcedeth: fix UAF of txrx_stats in nv_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: forcedeth: fix UAF of txrx_stats in nv_remove nv_remove() frees the per-CPU txrx_stats before unregister_netdev(). Until unregister completes, ndo_get_stats64, the NAPI/xmit data path, and nv_close()/drain may still access txrx_stats, leading to a use-after-free. Free the stats only after unregister_netdev().
