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...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerabilities have been resolved: net: lan743x: Fixed the memory leak issue when GSO is enabled. The skb has always been mapped to the LS descriptor. Previously, the skb was mapped to the EXT descriptor when the number of fragments was zero and GSO was enabled...
