CVE-2024-36931 s390/cio: Ensure the copied buf is NUL terminated

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...

CVE-2024-36931

The CVE-2024-36931 issue affects the Linux kernel on s390 architecture, specifically in s390/cio where a copied user buffer (lbuf-sized) is not guaranteed to be NUL-terminated before a scanf, enabling an out-of-bounds read. The root cause is missing termination inside the copied buffer, which is ...
