CVE-2025-38718

CVE-2025-38718 affects the Linux kernel SCTP implementation. The issue arises when cloning head skbs with fraglists, causing use-after-likes from sharing frag skbs and leading to uninitialized-value bugs (KMSAN) in sctp_inq_pop and related code paths. The fix patches sctp_rcv() to linearize clone...
