CVE-2024-38063
CVE-2024-38063 개요 2024년 8월, Microsoft는 Windows TCP/IP 원격 코드 실행RCE 취약점에 대한 패치를 발표했습니다. 일부 연구자들은 이미 이 취약점에 대한 개념 증명PoC을 공개했으며, 비슷한 시기에 PatchPoint 연구자들도 이 문제에 대한 분석 및 재현을 완료했습니다. Twitter를 포함한 다양한 플랫폼에서 잘못된 정보가 퍼져, 이 취약점을 트리거하는 데 필요한 핵심 사항이 오해된 것으로 보입니다. 이러한 부정확성과 달리, 우리는 단 두 개의 패킷 전송만으로 이 취약점이 트리거될 ...
CVE-2026-80875
In the Linux kernel , the IPVS (IP Virtual Server) subsystem contained a bug in TCP state lookup for IPv6 packets. The code reparsed the socket buffer to locate the TCP header using a fixed offset of sizeof(struct ipv6hdr), rather than the already-computed transport-header offset stored in iph.le...
EUVD-2026-71505
In the Linux kernel, the following vulnerability has been resolved: ipvs: use parsed transport offset in TCP state lookup TCP state handling reparses the skb to find the TCP header. For IPv6 it uses sizeofstruct ipv6hdr, while the surrounding IPVS code already parsed the packet with ipvsfilliphsk...

CVE-2026-72348
The CVE-2026-72348 entry concerns the Linux kernel netfilter ip6tables handling of IPv6 extension headers (ah, hbh, rt). The issue stems from checks that derive the advertised extension header length from header length fields; improper advertised-length checks allowed malformed headers to bypass ...

CVE-2026-72021
Summary: The CVE-2026-72021 issue affects the Linux kernel’s IPVS SCTP state lookup. The kernel incorrectly read the SCTP chunk header using a wrong offset for IPv6 when extension headers were present, causing misclassification of handshake steps (e.g., INIT1 vs ESTABLISHED) and incorrect managem...
