  "title": "Incorrect RST timeout handling in Linux netfilter conntrack",
  "summary": "Linux netfilter conntrack can apply a short closing timeout to an established TCP flow after receiving a reset packet that conntrack does not accept as closing the connection. An attacker able to inject suitable reset traffic into a targeted established flow may cause its conntrack entry to expire prematurely while both endpoints remain connected.",
  "mitigation": "Update Linux to version 6.18.61 or to a supported release containing one of the listed fixes. Until updated, reduce exposure to untrusted traffic that can inject TCP packets into established connections.",
