So, if, by some chance, our free_map and  \ntx_buff lists become out of sync then we were previously risking an  \nskb memory leak. This could then cause tcp congestion control to stop  \nsending packets, eventually leading to ETIMEDOUT.  \n  \nTherefore, add a conditional to ensure that the skb address is null. If  \nnot then warn the user (because this is still a bug that should be  \npatched) and free the old pointer to prevent memleak/tcp problems. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"29 Jul 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-07-29T17:58:10.000000Z"}]}
