If such a section is added to the firmware section list,\nsection->mem is left as NULL.\n\nLater reload and unplug paths iterate over all firmware sections and\ndereference section->mem, which can lead to a NULL pointer dereference.\n\nZero-sized firmware sections are valid, so accept them as no-op entries but\nskip adding them to the section list.","published":"2026-08-26T15:17:14.000Z","lastModified":"2026-08-26T15:17:14.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00209,"percentile":0.10926,"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":"unknown","text":"Not yet scored.
