Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipvs: Use the parsed transport offset in the TCP state lookup. The TCP state handling processes the skb again to find the TCP header. For IPv6, it uses sizeofstruct ipv6hdr. Meanwhile, the surrounding IPVS code has already parsed...

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...

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 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...

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...
