CVE-2025-38572 ipv6: reject malicious packets in ipv6_gso_segment()

In the Linux kernel, the following vulnerability has been resolved: ipv6: reject malicious packets in ipv6gsosegment syzbot was able to craft a packet with very long IPv6 extension headers leading to an overflow of skb-transportheader. This 16bit field has a limited range. Add...

kernel: net: fix udp gso skb_segment after pull from frag_list

A denial of service vulnerability has been discovered in the Linux kernel's UDP Generic Segmentation Offload GSO functionality. This flaw allows a local, unprivileged user to trigger a kernel crash by generating UDP packets with a specially malformed fraglist geometry. Successful exploitation of...

UBUNTU-CVE-2025-38331

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Use TOE/TSO on all TCP It is desireable to push the hardware accelerator to also process non-segmented TCP frames: we pass the skb-len to the "TOE/TSO" offloader and it will handle them. Without this quirk...
