If\nit hasn't found any memory it will return 0, allowing other memory\nsetup mechanisms to carry on.\n\nPreviously early_init_dt_scan_memory always returned 0 without\ndistinguishing between any kind of memory setup being done or not. Any\ncode path after the early_init_dt_scan memory call in the ramips\nplat_mem_setup code wouldn't be executed anymore. Making\nearly_init_dt_scan_memory the only way to initialize the memory.\n\nSome boards, including my mt7621 based Cudy X6 board, depend on memory\ninitialization being done via the soc_info.mem_detect function\npointer. Those wouldn't be able to obtain memory and panic the kernel\nduring early bootup with the message \"early_init_dt_alloc_memory_arch:\nFailed to allocate 12416 bytes align=0x40\".","published":"2025-09-17T15:15:37.000Z","lastModified":"2026-06-17T06:44:57.000Z","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-908"],"affected":["linux/linux kernel"],"epss":{"score":0.00205,"percentile":0.10413,"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 (0.21%).
