If walk_system_ram_range() reports more than\n16 memory ranges, the overflow call writes one struct maar_config past\nthe end of the array before WARN_ON() prevents num_cfg from advancing.\n\nMove the full-array check before taking the array slot and return non-zero\nwhen the scratch array is full, so walk_system_ram_range() terminates the\nwalk instead of invoking the callback for further ranges.","published":"2026-08-28T08:16:47.000Z","lastModified":"2026-08-28T08:16:47.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0022,"percentile":0.12394,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
