Bspec seems to be telling\nus to do this only in video mode, and this is also how the\nWindows driver does things.\n\nThis should also fix a div-by-zero on some machines because\nthe adjusted htotal ends up being so small that we end up with\nline_time_us==0 when trying to determine the vtotal value in\ncommand mode.\n\nNote that this doesn't actually make the display on the\nHuawei Matebook E work, but at least the kernel no longer\nexplodes when the driver loads.\n\n(cherry picked from commit 0b475e91ecc2313207196c6d7fd5c53e1a878525)","published":"2026-05-01T15:16:40.000Z","lastModified":"2026-10-21T13:18:42.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-369"],"affected":["linux/linux kernel"],"epss":{"score":0.0016,"percentile":0.05164,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.16%).
