CVE-2026-97609

The Linux kernel contains a use-after-free (UAF) vulnerability within the netfilter: cttimeout component during module unload. The issue occurs because cttimeout_exit() unregisters per-net operations before clearing the hook, allowing a race condition where one CPU can free the pernet storage whi...

SUSE CVE-2026-74347

In the Linux kernel, the following vulnerability has been resolved: netfilter: cttimeout: detach dataplane timeout policy and repurpose refcount Add a refcount for struct nfcttimeout which is used by ct extension to set the custom ct timeout policy, this tells us that the ct timeout is being used...

CVE-2026-74347

A flaw was found in the Linux kernel's netfilter cttimeout component. This issue arises from the improper management of connection tracking timeout policies. When an iptables ruleset continues to reference a connection tracking timeout policy, new connection tracking entries can repeatedly attach...

CVE-2026-74347

This CVE concerns the Linux kernel netfilter cttimeout handling. The fix adds a refcount for struct nf_ct_timeout used by the ct extension to track whether a conntrack entry uses the custom timeout policy, and then removes the control-plane refcount so the timeout policy can be removed immediatel...
