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...

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 found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: ipv6: Fixed warnings related to memcpy operations that span multiple fields in the AH output. These warnings occur when extension headers are copied to IPv6 address fields, causing Fortify-string warnings regarding writes...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, 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-2026-72348

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...
