{"id":"CVE-2023-23005","details":"In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached.","modified":"2026-03-15T14:49:23.584379Z","published":"2023-03-01T20:15:15.100Z","references":[{"type":"FIX","url":"https://bugzilla.suse.com/show_bug.cgi?id=1208844#c2"},{"type":"FIX","url":"https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/4a625ceee8a0ab0273534cb6b432ce6b331db5ee"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.2"}]},{"events":[{"introduced":"0"},{"last_affected":"15-sp5"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-23005.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
