CVE-2025-37937
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:
drivers/media/dvb-frontends/dib8000.o: warning: objtool: dib8000_tune() falls through to next function dib8096p_cfg_DibRx()
