CVE-2025-39677

CVE-2025-39677: In the Linux kernel, backlog accounting was fixed for qdisc_dequeue_internal affecting tbf-backed qdiscs (hhf, fq, fq_codel, fq_pie). The root cause was that when dropping packets to satisfy a new limit, only qlen was accounted for for some cases (gso_skb path), omitting qdisc_qst...

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...
