0 : 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. (string)

1 : A flaw was found in the Linux kernel’s cio_inject module. Data from the user space is copied to a kernel buffer without making sure it is NULL terminated, causing an out-of-bounds read and resulting in a denial of service. (string)
