When msg[i].buf\nis null and msg[i].len is zero, former checks on msg[i].buf would be\npassed. Malicious data finally reach af9005_i2c_xfer. If accessing\nmsg[i].buf[0] without sanity check, null ptr deref would happen.\nWe add check on msg[i].len to prevent crash.\n\nSimilar commit:\ncommit 0ed554fd769a\n(\"media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()\")","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/033b0c0780adee32dde218179e9bc51d2525108f","https://git.kernel.org/stable/c/0c02eb70b1dd4ae9bb304ce6cdadbc6faba2b2e9","https://git.kernel.org/stable/c/63d962ac7a52c0ff4cd09af2e284dce5e5955dfe","https://git.kernel.org/stable/c/98c12abb275b75a98ff62de9466d21e4daa98536","https://git.kernel.org/stable/c/abb6fd93e05e80668d2317fe1110bc99b05034c3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:18:08.089039631+00:00"},"epss":{"cve":"CVE-2023-54314","score":0.00198,"percentile":0.09601,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
