However, some of the processing occurs before the buffer is authenticated. The function will return various types of errors depending on the values of the `response` and `result` fields of the buffer before verifying the HMAC tag.","published":"2018-04-18T14:29:11.000Z","lastModified":"2026-06-17T00:39:41.000Z","status":"Modified","sourceIdentifier":"product-security@qualcomm.com","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-287"],"affected":["qualcomm/sd 820 firmware","qualcomm/sd 820a firmware"],"epss":{"score":0.00795,"percentile":0.56176,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.80%).
