Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: qedi: Fix crash while reading debugfs attribute The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash. To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.
