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","state":0,"publishedAt":"2026-10-23T12:05:54.511+00:00","modifiedAt":"2026-10-23T12:05:54.511+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/gpu/drm/amd/display/dc/link/link_dpms.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n                            \"lessThan\": \"0b1eebd359685dd681f6e0df5540a5bb985a27bf\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n                            \"lessThan\": \"8fa813b7fd1eccbed13e126166cf764f1f11a7d3\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.2.9\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/gpu/drm/amd/display/dc/link/link_dpms.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.2.9\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/0b1eebd359685dd681f6e0df5540a5bb985a27bf","https://git.kernel.org/stable/c/8fa813b7fd1eccbed13e126166cf764f1f11a7d3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98926","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98926","identifiers":["CVE-2026-98926"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
