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