n the Linux kernel, the following vulnerability has been resolved: media: vivid: fix buffer overwrite when using > 32 buffers The maximum number of buffers that can be requested was increased to 64 for the video capture queue. But video capture used a must_blank array that was still sized for 32 (VIDEO_MAX_FRAME). This caused an out-of-bounds write when using buffer indices >= 32. Create a new define MAX_VID_CAP_BUFFERS that is used to access the must_blank array and set max_num_buffers for the video capture queue. This solves a crash reported by: https://bugzilla.kernel.org/show_bug.cgi?id=219258

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: vivid: se corrige la sobrescritura de búfer al usar > 32 búferes. La cantidad máxima de búferes que se pueden solicitar se aumentó a 64 para la cola de captura de video. Pero la captura de video usó una matriz must_blank que todavía tenía un tamaño de 32 (VIDEO_MAX_FRAME). Esto provocó una escritura fuera de los límites cuando se usan índices de búfer >= 32. Cree una nueva definición 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
