Use copy_from_user() instead so a non-user address is\nrejected and the entry is recorded as faulted.\n\nIt could be a security concern for machines that trust perf a bit too\nmuch.","published":"2026-11-02T16:17:48.247000+00:00","modified":"2026-11-02T16:17:48.247000+00:00","status":"Received","score":null,"severity":"UNSCORED","vector":"","cvss_version":"","affected":[],"weaknesses":[],"references":[{"url":"https://git.kernel.org/stable/c/041d1a568a11a7ed7415ef1408d0c65041c1ad69","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/e33e2718c62a602001ab549642a1aed0be797105","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}],"kev":null,"kev_checked":true,"metrics":{},"configurations":[],"source":"nvd","retrieved_at":"2026-11-02T19:29:45.084978+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/041d1a568a11a7ed7415ef1408d0c65041c1ad69","investigate_url":"https://investigate.aeglixmind.com/#git.kernel.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-99232","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-99232","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-99232","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
