Descriptions

In the Linux kernel, the following vulnerability has been resolved:

speakup: Fix sizeof() vs ARRAY_SIZE() bug

The "buf" pointer is an array of u16 values. This code should be
using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512),
otherwise it can the still got out of bounds.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Speakup: corrige el error sizeof() vs ARRAY_SIZE() El puntero "buf" es una matriz de valores u16. Este código debería usar ARRAY_SIZE() (que es 256) en lugar de sizeof() (que es 512), de lo contrario aún puede salirse de los límites.
