"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: vivid: fix buffer overwrite when using > 32 buffers\n\nThe maximum number of buffers that can be requested was increased to\n64 for the video capture queue. But video capture used a must_blank\narray that was still sized for 32 (VIDEO_MAX_FRAME). This caused an\nout-of-bounds write when using buffer indices >= 32.\n\nCreate a new define MAX_VID_CAP_BUFFERS that is used to access the\nmust_blank array and set max_num_buffers for the video capture queue.\n\nThis solves a crash reported by:\n\n\thttps://bugzilla.kernel.org/show_bug.cgi?id=219258"

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: vivid: se corrige la sobrescritura de b\u00fafer al usar > 32 b\u00faferes. La cantidad m\u00e1xima de b\u00faferes que se pueden solicitar se aument\u00f3 a 64 para la cola de captura de video. Pero la captura de video us\u00f3 una matriz must_blank que todav\u00eda ten\u00eda un tama\u00f1o de 32 (VIDEO_MAX_FRAME). Esto provoc\u00f3 una escritura fuera de los l\u00edmites cuando se usan \u00edndices de b\u00fafer >= 32. Cree una nueva definici\u00f3n MAX_VID_CAP_BUFFERS que se use para acceder a la matriz must_blank y establezca max_num_buffers para la cola de captura de video. Esto resuelve un bloqueo informado por: https://bugzilla.kernel.org/show_bug.cgi?id=219258"
