CVE-2025-38718 is a Linux kernel SCTP receive-path vulnerability affecting processing of cloned Generic Segmentation Offload (GSO) packets in sctp_rcv(). A cloned head socket buffer can share fragment-list socket buffers with the original head buffer. Access to those shared fragments is unsafe and caused KMSAN-reported use-of-uninitialized-memory conditions in SCTP input processing. The upstream correction linearizes cloned GSO packets before they are processed by SCTP.
