CVE-2024-38063

CVE-2024-38063 概述 2024年8月，微软发布了针对Windows TCP/IP远程代码执行RCE漏洞的补丁。一些研究人员已经发布了该漏洞的概念验证PoC，与此同时，PatchPoint的研究人员也完成了对该问题的分析和复现。由于包括Twitter在内的多个平台上存在错误信息的传播，触发该漏洞所需的关键点似乎被误解了。与这些不准确的信息相反，我们决定发布一个PoC，演示如何仅通过发送两个数据包即可触发该漏洞。实际上，触发该漏洞并不需要大量的数据包。 PoC from scapy.all import IPAddr = '' fe80::XXXX:XXXX:XXXX:XXXX...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Properly handles tunneled traffic when using GSO fallback for IPV6CSUM. NETIFFIPV6CSUM only indicates support for packet checksum offloading without IPv6 extension headers. Packets with extension headers must rely on...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: icmp6: Fixed the null-ptr-deref of ip6nullentry-rt6iidev in icmp6dev. With some IPv6 Ext Hdr RPL, SRv6, etc., we can send a packet that has the link-local address as src and dst IP, and it will be forwarded to an external IP in t...

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...
