CVE-2026-72017

Summary: CVE-2026-72017 affects the Linux kernel MACB driver (net: macb: drop in-flight Tx SKBs on close). The issue is a leak of outgoing SKBs held in queue->tx_skb, which are freed without proper checks. The leak is triggered via macb_free_consistent() in certain paths, with open/alloc_consi...
