For TCP, this \ncauses a NULL ptr deref in __tcpv4_gso_segment_list_csum at \ntcp_hdr(seg->next). \n \nDetect invalid geometry due to pull, by checking head_skb size. \nDon't just drop, as this may blackhole a destination. Convert to be \nable to pass to regular skb_segment. \n \nApproach and description based on a patch by Willem de Bruijn. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"21 Oct 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-10-21T21:02:17.000000Z"} 2024-10-21T21:02:17+00:00
