It’s a proprietary config file. I think it’s a list of rules to forbid certain behaviours on the system. Presumably it’s downloaded by some userland service, but it has to be parsed by the kernel driver. I think the files get loaded ok but the driver crashes when iterating over an array of pointers. Possibly these are the rules and some have uninitialised pointers but this is speculation based on some kernel dumps on twitter. So the bug probably existed in the kernel driver for quite a while, but they pushed a (somehow) malformed config file that triggered the crash.
To be clear, the record label is Death Row Records. He was initially charged with attempted murder but that was dropped and he wasn’t ever facing the death penalty. He was behind bars for 33 years for running a “nationwide drug trafficking operation that brought in nearly $2 million daily.” Snoop now owns Death Row Records.
