It causes an out-of-bounds read from 'trans->tx_buf' (which has size\n   'trans->len', i.e., 'len - 1' in this context).\n2. It can cause an out-of-bounds write to 'ch341->tx_buf' if 'len' is\n   CH341_PACKET_LENGTH (32). Writing 32 bytes to ch341->tx_buf + 1\n   overflows the buffer.\n\nFix this by copying 'len - 1' bytes.","published":"2025-12-24T11:15:59.000Z","lastModified":"2026-10-19T21:10:00.000Z","status":"Deferred","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00153,"percentile":0.04412,"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 (0.15%).
