Descriptions
In the Linux kernel, the following vulnerability has been resolved:
s390/cio: Ensure the copied buf is NUL terminated
Currently, we allocate a lbuf-sized kernel buffer and copy lbuf from
userspace to that buffer. Later, we use scanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using scanf. Fix this issue by using memdup_user_nul instead.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: s390/cio: asegúrese de que el buf copiado tenga terminación NUL. Actualmente, asignamos un búfer del kernel del tamaño de lbuf y copiamos lbuf del espacio de usuario a ese búfer. Más adelante, usamos scanf en este búfer pero no nos aseguramos de que la cadena termine dentro del búfer, esto puede provocar una lectura OOB cuando usamos scanf. Solucione este problema utilizando memdup_user_nul en su lugar.
