Descriptions

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

riscv: Fix TASK_SIZE on 64-bit NOMMU

On NOMMU, userspace memory can come from anywhere in physical RAM. The
current definition of TASK_SIZE is wrong if any RAM exists above 4G,
causing spurious failures in the userspace access routines.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv: corrige TASK_SIZE en NOMMU de 64 bits En NOMMU, la memoria del espacio de usuario puede provenir de cualquier lugar de la RAM física. La definición actual de TASK_SIZE es incorrecta si existe RAM por encima de 4G, lo que provoca fallos falsos en las rutinas de acceso al espacio de usuario.
