CVE-2026-23048: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: udp: call skb_orphan() before skb_attempt_defer_free() Standard UDP receive path does not use skb->destructor. But skmsg layer does use it, since it calls skb_set_owner_sk_safe() from udp_read_skb(). This then triggers this warning in skb_attempt_defer_free(): DEBUG_NET_WARN_ON_ONCE(skb->destructor); We must call skb_orphan() to fix this issue.
