CVE-2026-98625

The Linux kernel contains a use-after-free vulnerability within the netfilter flowtable component. The issue resides in flow_offload_work_del(), which incorrectly sets the NF_FLOW_HW_DEAD bit before clearing the NF_FLOW_HW_PENDING bit. Because the offload worker lacks an RCU read lock or a flow r...
