In the Linux kernel, the following vulnerability has been resolved:
objtool, media: dib8000: Prevent divide-by-zero in dib8000setdds()
If dib8000setdds()'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: dib8000tune() falls through to next function dib8096pcfg_DibRx()
