Descriptions

In the Linux kernel, the following vulnerability has been resolved: ataflop: potential out of bounds in do_format() The function uses "type" as an array index: q = unit[drive].disk[type]->queue; Unfortunately the bounds check on "type" isn't done until later in the
function. Fix this by moving the bounds check to the start.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: ataflop: potencial fuera de los límites en do_format() La función utiliza "tipo" como índice de matriz: q = unidad[unidad].disco[tipo]->cola; Desafortunadamente, la verificación de los límites en "tipo" no se realiza hasta más adelante en la función. Solucione este problema moviendo la verificación de los límites al inicio.
