      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: mtk_eth_soc: Fix use-after-free in metadata dst teardown\n\nmtk_free_dev() calls metadata_dst_free() which frees the metadata_dst\nwith kfree() immediately, bypassing the RCU grace period.\nIn the RX path, skb_dst_set_noref() sets a non-refcounted pointer from\nthe skb to the metadata_dst. This function requires RCU read-side\nprotection and the dst must remain valid until all RCU readers complete.\nSince metadata_dst_free() calls kfree() directly, a use-after-free can\noccur if any skb still holds a noref pointer to the dst when the driver\ntears it down.\nReplace metadata_dst_free() with dst_release() which properly goes\nthrough the refcount path: when the refcount drops to zero, it schedules\nthe actual free via call_rcu_hurry(), ensuring all RCU readers have\ncompleted before the memory is freed.",
