Jann Horn 2638a67a0c USB: yurex: fix out-of-bounds uaccess in read handler ... commit f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 upstream. In general, accessing userspace memory beyond the length of the supplied buffer in VFS read/write handlers can lead to both kernel memory corruption (via kernel_read()/kernel_write(), which can e.g. be triggered via sys_splice()) and privilege escalation inside userspace. Fix it by using simple_read_from_buffer() instead of custom logic.
