This mechanism needs a\nstruct device to work so fwnode-based lookup with no device associated\ncurrently causes a NULL-pointer deference.\n\nAdding this functionality will require a larger rework and it has never\nworked anyway so add a check that allows the kernel to gracefully handle\nthis situation with an error ahead of implementing that functionality as\na new feature.","published":"2026-11-03T12:17:32.590000+00:00","modified":"2026-11-03T12:17:32.590000+00:00","status":"Received","score":null,"severity":"UNSCORED","vector":"","cvss_version":"","affected":[],"weaknesses":[],"references":[{"url":"https://git.kernel.org/stable/c/7f9eb6aaf9a3ab7fa2b7dcc38660c27db12d4ec1","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/cf73c3fc03c43a8a86fd487c62390b4744eff9ec","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}],"kev":null,"kev_checked":true,"metrics":{},"configurations":[],"source":"nvd","retrieved_at":"2026-11-03T15:35:05.952401+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence.","Fresh EPSS data is unavailable; missing values are not zero."]},"epss":null,"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"git.kernel.org","source_url":"https://git.kernel.org/stable/c/7f9eb6aaf9a3ab7fa2b7dcc38660c27db12d4ec1","investigate_url":"https://investigate.aeglixmind.com/#git.kernel.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-99257","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-99257","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-99257","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
