HIGH Summary
In the Linux kernel, the following vulnerability has been resolved: netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write() This was found by a static analyzer. We should not forget the trailing zero after copy_from_user() if we will further do some string operations, sscanf() in this case. Adding a trailing zero will ensure that the function performs properly.

- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
