"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Remove sink usage from DPMS\n\n[Why]\nstream->sink is optional and can be null, so should always be checked\nbefore dereference. Additionally, most of its usage in DPMS sequences\nis for stream->sink->link, which can be replaced with stream->link,\nas the two should always be the same.\n\n[How]\n* Replace stream->sink->link in DPMS on/off\n* Add assert to USB4 BW allocation where sink is required\n* Avoid inconsistencies in resource access, e.g. don't repeat\nstream->link after it was already saved to a local variable\n* Pull out effective VPG calculation to helper getter\n* Formatting fixes"
