CVE-2025-37937

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds()

If dib8000_set_dds()'s call to dib8000_read32() returns zero, the result is a divide-by-zero. Prevent that from happening.

Fixes the following warning with an UBSAN kernel:
