CVE-2025-38718

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to the handling of cloned GSO (Generic Segmentation Offload) packets within the SCTP (Stream Control Transmission Protocol) stack. Specifically, a cloned head skb (socket buffer) continues to share frag skbs (fragment socket buffers) in its fraglist with the original head skb, leading to potential use-of-uninitialized-memory issues. This condition was identified through syzbot reports, indicating potential bugs in functions such as sctp inq pop, sctp assoc bh rcv, sctp inq push, and sctp backlog rcv.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
