CVE-2021-47642

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> video: fbdev: nvidiafb: Use strscpy() to prevent buffer overflow<br /> <br /> Coverity complains of a possible buffer overflow. However,<br /> given the &amp;#39;static&amp;#39; scope of nvidia_setup_i2c_bus() it looks<br /> like that can&amp;#39;t happen after examiniing the call sites.<br /> <br /> CID 19036 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)<br /> 1. fixed_size_dest: You might overrun the 48-character fixed-size string<br /> chan-&gt;adapter.name by copying name without checking the length.<br /> 2. parameter_as_source: Note: This defect has an elevated risk because the<br /> source argument is a parameter of the current function.<br /> 89 strcpy(chan-&gt;adapter.name, name);<br /> <br /> Fix this warning by using strscpy() which will silence the warning and<br /> prevent any future buffer overflows should the names used to identify the<br /> channel become much longer.
