Therefore, partial\nallocation should not be treated as a fatal error.\n\nModify es58x_alloc_rx_urbs() to return 0 if at least one URB has been\nallocated, restoring the intended behavior and preventing the leak\nin es58x_open().","published":"2026-01-31T12:16:07.000Z","lastModified":"2026-06-17T10:20:45.000Z","status":"Deferred","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00243,"percentile":0.15373,"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.
