Linux Kernel DIB8000 Media Driver Divide-By-Zero Vulnerability

Vulnerability

A divide-by-zero vulnerability has been identified in the Linux kernel's media DIB8000 driver. The issue arises in the 'dib8000_set_dds()' function, where a call to 'dib8000_read32()' can return zero, leading to a division by zero error. This vulnerability triggers a warning in the Undefined Behavior Sanitizer (UBSAN) enabled kernel.
