"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: mana: Fix RX buf alloc_size adjustment and atomic op panic El b\u00fafer RX alloc_size del controlador MANA se pasa a napi_build_skb() para crear SKB. skb_shinfo(skb) se encuentra al final de skb, y su alineaci\u00f3n se ve afectada por el alloc_size pasado a napi_build_skb().
