Descriptions

In the Linux kernel, the following vulnerability has been resolved: block: fix overflow in blk_ioctl_discard() There is no check for overflow of 'start + len' in blk_ioctl_discard().
Hung task occurs if submit an discard ioctl with the following param: start = 0x80000000000ff000, len = 0x8000000000fff000;
Add the overflow validation now.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: corrige el desbordamiento en blk_ioctl_discard() No hay verificación de desbordamiento de 'start + len' en blk_ioctl_discard(). La tarea bloqueada ocurre si envía un ioctl de descarte con el siguiente parámetro: start = 0x80000000000ff000, len = 0x8000000000fff000; Agregue la validación de desbordamiento ahora.
