      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211_hwsim: clamp virtio RX length before skb_put\n\nhwsim_virtio_rx_work() passes the virtqueue used-ring length reported by\nthe device straight to skb_put() on a fixed-size receive skb. A backend\nreporting a length larger than the skb tailroom drives skb_put() past the\nbuffer end and hits skb_over_panic() -- a host-triggerable guest panic\n(denial of service).\n\nClamp the length to the skb's available room before skb_put(). A\nconforming device never reports more than the posted buffer size, so valid\nframes are unaffected; a truncated over-report then fails the\nlength/header checks in hwsim_virtio_handle_cmd() and is dropped, so\ntruncating rather than dropping here cannot be turned into a parsing\nproblem.",
