kernel: netfilter: flowtable: hold reference on ct until flow is released

A flaw was found in the Linux kernel's netfilter subsystem. In the flowtable component, connection tracking reference counts are prematurely released before flow entries are fully removed from memory. An attacker could exploit this timing issue during network flow processing, triggering a...

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...
