      "value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: Vuelva a aplicar \"drm/qxl: simplificar qxl_fence_wait\" Esto revierte el commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt informa: \"Fui a ejecutar mis pruebas en mis m\u00e1quinas virtuales y las pruebas se colgaron al arrancar. Desafortunadamente, lo m\u00e1ximo que obtuve fue: [ 93.607888] Probando evento de initcall del sistema: OK [ 93.667730] Ejecutando pruebas en todos los eventos de seguimiento : [93.669757] Probando todos los eventos: OK [95.631064] ------------[ cortar aqu\u00ed ]------------ Se agot\u00f3 el tiempo de espera despu\u00e9s de 60 segundos\" y m\u00e1s puntos de depuraci\u00f3n a una posible dependencia de bloqueo circular entre el bloqueo del propietario de la consola y el bloqueo del grupo de trabajadores. Revertir el commit permite que la m\u00e1quina virtual de Steve se inicie nuevamente. [Obviamente, esto puede provocar que aparezcan nuevamente los mensajes \"[TTM] Error en el desalojo del b\u00fafer\", que fue el motivo de la reversi\u00f3n original. Pero en este punto esto parece preferible a un sistema sin arranque...]"
